Note on Resolve-Path:
All paths are sent through Resolve-Path/Resolve-PSFPath in order to convert them to the correct path separator.
This allows ignoring path separators throughout the import sequence, which could otherwise cause trouble depending on OS.
Resolve-Path can only be used for paths that already exist, Resolve-PSFPath can accept that the last leaf my not exist.
This is important when testing for paths.

<#
    .SYNOPSIS
        Get data from an Data Entity using OData
         
    .DESCRIPTION
        Get data from an Data Entity using the OData endpoint of the Dynamics 365 Customer Engagement
         
    .PARAMETER EntityName
        Name of the Data Entity you want to work against
         
        The parameter is Case Sensitive, because the OData endpoint in D365CE is Case Sensitive
         
        Remember that most Data Entities in a D365CE environment is named by its singular name, but most be retrieve using the plural name
         
        E.g. The account Data Entity is named "account", but can only be retrieving using "accounts"
         
        Use the XRMToolBox (https://www.xrmtoolbox.com) to help you identify the names of the Data Entities that you are looking for
         
    .PARAMETER EntitySetName
        Name of the Data Entity you want to work against
         
        The parameter is created specifically to be used when piping from Get-D365CeODataPublicEntity
         
    .PARAMETER ODataQuery
        Valid OData query string that you want to pass onto the D365 OData endpoint while retrieving data
         
        OData specific query options are:
        $filter
        $expand
        $select
        $orderby
        $top
        $skip
         
        Each option has different characteristics, which is well documented at: http://docs.oasis-open.org/odata/odata/v4.0/odata-v4.0-part2-url-conventions.html
         
    .PARAMETER Charset
        The charset / encoding that you want the cmdlet to use while fetching the odata entity
         
        The default value is: "UTF8"
         
        The charset has to be a valid http charset like: ASCII, ANSI, ISO-8859-1, UTF-8
         
    .PARAMETER Tenant
        Azure Active Directory (AAD) tenant id (Guid) that the D365CE environment is connected to, that you want to access through OData
         
    .PARAMETER Url
        URL / URI for the D365CE environment you want to access through OData
         
    .PARAMETER ClientId
        The ClientId obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER ClientSecret
        The ClientSecret obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER FullODataMeta
        Instruct the cmdlet to request all metadata to be filled into the payload
         
        Useful when you are looking for navigation properties and linked entities
         
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions
        This is less user friendly, but allows catching exceptions in calling scripts
         
    .PARAMETER RawOutput
        Instructs the cmdlet to include the outer structure of the response received from OData endpoint
         
        The output will still be a PSCustomObject
         
    .PARAMETER OutputAsJson
        Instructs the cmdlet to convert the output to a Json string
         
    .EXAMPLE
        PS C:\> Get-D365CeODataEntityData -EntityName accounts -ODataQuery '$top=1'
         
        This will get Accounts from the OData endpoint.
        It will use the "Account" entity, and its EntitySetName / CollectionName "accounts".
        It will get the top 1 results from the list of accounts.
         
        It will use the default OData configuration details that are stored in the configuration store.
         
    .EXAMPLE
        PS C:\> Get-D365CeODataEntityData -EntityName accounts -ODataQuery '$top=1' -FullODataMeta
         
        This will get Accounts, and include all metadata, from the OData endpoint.
        It will use the "Account" entity, and its EntitySetName / CollectionName "accounts".
        It will get the top 1 results from the list of accounts.
         
        It will use the default OData configuration details that are stored in the configuration store.
         
    .EXAMPLE
        PS C:\> Get-D365CeODataEntityData -EntityName accounts -ODataQuery '$top=10&$filter=address1_city eq ''New York'''
         
        This will get Accounts from the OData endpoint.
        It will use the Account entity, and its EntitySetName / CollectionName "Accounts".
        It will get the top 10 results from the list of accounts.
        It will filter the entities for records where the "address1_city" is 'New York'.
         
        It will use the default OData configuration details that are stored in the configuration store.

    .NOTES
        The OData standard is using the $ (dollar sign) for many functions and features, which in PowerShell is normally used for variables.
         
        Whenever you want to use the different query options, you need to take the $ sign and single quotes into consideration.
         
        Example of an execution where I want the top 1 result only, with a specific city filled out.
        This example is using single quotes, to help PowerShell not trying to convert the $ into a variable.
        Because the OData standard is using single quotes as text qualifiers, we need to escape them with multiple single quotes.

    .SYNOPSIS
        Import a Data Entity into Dynamics 365 Customer Engagement
         
    .DESCRIPTION
        Imports a Data Entity, defined as a json payload, using the OData endpoint of the Dynamics 365 Customer Engagement
         
    .PARAMETER EntityName
        Name of the Data Entity you want to work against
         
        The parameter is Case Sensitive, because the OData endpoint in D365CE is Case Sensitive
         
        Remember that most Data Entities in a D365CE environment is named by its singular name, but most be retrieve using the plural name
         
        E.g. The account Data Entity is named "account", but can only be retrieving using "accounts"
         
        Use the XRMToolBox (https://www.xrmtoolbox.com) to help you identify the names of the Data Entities that you are looking for
         
    .PARAMETER Payload
        The entire string contain the json object that you want to import into the D365CE environment
         
        Remember that json is text based and can use either single quotes (') or double quotes (") as the text qualifier, so you might need to escape the different quotes in your payload before passing it in
         
    .PARAMETER PayloadCharset
        The charset / encoding that you want the cmdlet to use while importing the odata entity
         
        The default value is: "UTF8"
         
        The charset has to be a valid http charset like: ASCII, ANSI, ISO-8859-1, UTF-8
         
    .PARAMETER RefPath
        Path for working with the referene capabilities of the OData endpoint
         
        Can be used to map / assiociate an entity to another, like systemuser to a role
         
    .PARAMETER Tenant
        Azure Active Directory (AAD) tenant id (Guid) that the D365CE environment is connected to, that you want to access through OData
         
    .PARAMETER Url
        URL / URI for the D365CE environment you want to access through OData
         
    .PARAMETER ClientId
        The ClientId obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER ClientSecret
        The ClientSecret obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions
        This is less user friendly, but allows catching exceptions in calling scripts
         
    .EXAMPLE
        PS C:\> Import-D365CeODataEntity -EntityName "ExchangeRates" -Payload '{"@odata.type" :"Microsoft.Dynamics.DataEntities.ExchangeRate", "RateTypeName": "TEST", "FromCurrency": "DKK", "ToCurrency": "EUR", "StartDate": "2019-01-03T00:00:00Z", "Rate": 745.10, "ConversionFactor": "Hundred", "RateTypeDescription": "TEST"}'
         
        This will import a Data Entity into Dynamics 365 Customer Engagement using the OData endpoint.
        The EntityName used for the import is ExchangeRates.
        The Payload is a valid json string, containing all the needed properties.
         
    .EXAMPLE
        PS C:\> $Payload = '{"@odata.type" :"Microsoft.Dynamics.DataEntities.ExchangeRate", "RateTypeName": "TEST", "FromCurrency": "DKK", "ToCurrency": "EUR", "StartDate": "2019-01-03T00:00:00Z", "Rate": 745.10, "ConversionFactor": "Hundred", "RateTypeDescription": "TEST"}'
        PS C:\> Import-D365CeODataEntity -EntityName "ExchangeRates" -Payload $Payload
         
        This will import a Data Entity into Dynamics 365 Customer Engagement using the OData endpoint.
        First the desired json data is put into the $Payload variable.
        The EntityName used for the import is ExchangeRates.
        The $Payload variable is passed to the cmdlet.
         
    .EXAMPLE
        PS C:\> $Payload = '{"@odata.id":"[Organization URI]/api/data/v9.0/roles(00000000-0000-0000-0000-000000000001)"}'
        PS C:\> Import-D365CeODataEntity -EntityName "systemusers" -Payload $Payload -RefPath '(00000000-0000-0000-0000-000000000002)/systemuserroles_association/$ref'
         
        This will create a referene between the systemusers Data Entity and the systemuserroles in Dynamics 365 Customer Engagement using the OData endpoint.
        First the desired json data is put into the $Payload variable.
        The EntityName used for the import is systemusers.
        The RefPath '(00000000-0000-0000-0000-000000000002)/systemuserroles_association/$ref' is the systemuser "00000000-0000-0000-0000-000000000002" which you want to associate with the role "00000000-0000-0000-0000-000000000001"
        The $Payload variable is passed to the cmdlet.

    .SYNOPSIS
        Remove a Data Entity from Dynamics 365 Customer Engagement
         
    .DESCRIPTION
        Removes a Data Entity, defined by the EntityKey, using the OData endpoint of the Dynamics 365 Customer Engagement
         
    .PARAMETER EntityName
        Name of the Data Entity you want to work against
         
        The parameter is Case Sensitive, because the OData endpoint in D365CE is Case Sensitive
         
        Remember that most Data Entities in a D365CE environment is named by its singular name, but most be retrieve using the plural name
         
        E.g. The account Data Entity is named "account", but can only be retrieving using "accounts"
         
        Use the XRMToolBox (https://www.xrmtoolbox.com) to help you identify the names of the Data Entities that you are looking for
         
    .PARAMETER Key
        The key that will select the desired Data Entity uniquely across the OData endpoint
         
        The key would most likely be made up from multiple values, but can also be a single value
         
    .PARAMETER RefPath
        Path for working with the referene capabilities of the OData endpoint
         
        Can be used to unmap / deassiociate an entity from another, like removing a systemuser from a role
         
    .PARAMETER Tenant
        Azure Active Directory (AAD) tenant id (Guid) that the D365CE environment is connected to, that you want to access through OData
         
    .PARAMETER Url
        URL / URI for the D365CE environment you want to access through OData
         
    .PARAMETER ClientId
        The ClientId obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER ClientSecret
        The ClientSecret obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions
        This is less user friendly, but allows catching exceptions in calling scripts
         
    .EXAMPLE
        PS C:\> Remove-D365CeODataEntity -EntityName ExchangeRates -EntityKey "RateTypeName='TEST'","FromCurrency='DKK'","ToCurrency='EUR'","StartDate=2019-01-13T12:00:00Z"
         
        This will remove a Data Entity from the D365CE environment through OData.
        It will use the ExchangeRate entity, and its EntitySetName / CollectionName "ExchangeRates".
        It will use the "RateTypeName='TEST'","FromCurrency='DKK'","ToCurrency='EUR'","StartDate=2019-01-13T12:00:00Z" as the unique key for the entity.
         
        It will use the default OData configuration details that are stored in the configuration store.
         
    .EXAMPLE
        PS C:\> Remove-D365CeODataEntity -EntityName "systemusers" -Key "00000000-0000-0000-0000-000000000002" -RefPath '/systemuserroles_association(00000000-0000-0000-0000-000000000001)/$ref'
         
        This will remove the mapping / association between 2 Data Entities from the D365CE environment through OData.
        The EntityName is "systemusers" which is the user, that you want to remove from a role.
        The Key "00000000-0000-0000-0000-000000000002" is the unique systemuserid for the user that you want to work against.
        The RefPath '/systemuserroles_association(00000000-0000-0000-0000-000000000001)/$ref' points to the unique roleid that you want to remove the user from.
         
        It will use the default OData configuration details that are stored in the configuration store.

<#
    .SYNOPSIS
        Update a Data Entity in Dynamics 365 Customer Engagement
         
    .DESCRIPTION
        Updates a Data Entity, defined as a json payload, using the OData endpoint of the Dynamics 365 Customer Engagement platform
         
    .PARAMETER EntityName
        Name of the Data Entity you want to work against
         
        The parameter is Case Sensitive, because the OData endpoint in D365CE is Case Sensitive
         
        Remember that most Data Entities in a D365CE environment is named by its singular name, but most be retrieve using the plural name
         
        E.g. The account Data Entity is named "account", but can only be retrieving using "accounts"
         
        Use the XRMToolBox (https://www.xrmtoolbox.com) to help you identify the names of the Data Entities that you are looking for
         
    .PARAMETER Key
        The key that will select the desired Data Entity uniquely across the OData endpoint
         
        The key would most likely be made up from multiple values, but can also be a single value
         
    .PARAMETER Payload
        The entire string contain the json object that you want to import into the D365CE environment
         
        Remember that json is text based and can use either single quotes (') or double quotes (") as the text qualifier, so you might need to escape the different quotes in your payload before passing it in
         
    .PARAMETER PayloadCharset
        The charset / encoding that you want the cmdlet to use while updating the odata entity
         
        The default value is: "UTF8"
         
        The charset has to be a valid http charset like: ASCII, ANSI, ISO-8859-1, UTF-8
         
    .PARAMETER PayloadCharset
        The charset / encoding that you want the cmdlet to use while importing the odata entity
         
        The default value is: "UTF8"
         
        The charset has to be a valid http charset like: ASCII, ANSI, ISO-8859-1, UTF-8
         
    .PARAMETER Tenant
        Azure Active Directory (AAD) tenant id (Guid) that the D365CE environment is connected to, that you want to access through OData
         
    .PARAMETER Url
        URL / URI for the D365CE environment you want to access through OData
         
    .PARAMETER ClientId
        The ClientId obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER ClientSecret
        The ClientSecret obtained from the Azure Portal when you created a Registered Application
         
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions
        This is less user friendly, but allows catching exceptions in calling scripts
         
    .EXAMPLE
        PS C:\> Update-D365CeODataEntity -EntityName "accounts" -Key "accountid=4b306dc7-ab04-4ddf-b18d-d75ffa2dba2c" -Payload '{"address2_city": "Chicago"}'
         
        This will update a Data Entity in Dynamics 365 Customer Engagement using the OData endpoint.
        The EntityName used for the import is "accounts".
        It will use the "accountid=4b306dc7-ab04-4ddf-b18d-d75ffa2dba2c" as key to identify the unique Account record.
        The Payload is a valid json string, containing the needed properties that we want to update.
         
        It will use the default OData configuration details that are stored in the configuration store.
         
    .EXAMPLE
        PS C:\> $Payload = '{"address2_city": "Chicago"}'
        PS C:\> Update-D365CeODataEntity -EntityName "accounts" -Key "accountid=4b306dc7-ab04-4ddf-b18d-d75ffa2dba2c" -Payload $Payload
         
        This will update a Data Entity in Dynamics 365 Customer Engagement using the OData endpoint.
        First the desired json data is put into the $Payload variable.
        The EntityName used for the import is "accounts".
        It will use the "accountid=4b306dc7-ab04-4ddf-b18d-d75ffa2dba2c" as key to identify the unique Account record.
        The $Payload variable is passed to the cmdlet.
         
        It will use the default OData configuration details that are stored in the configuration store.

without having to maintain it in separate locations.
 
It also prevents lengthy validation scriptblocks from making your parameter block
