<#
    .SYNOPSIS
        Compare the environment users
         
    .DESCRIPTION
        This enables the user to compare 2 x environments, with one as a source and the other as a destination
         
        It will only look for users on the source, and use this as a baseline against the destination
         
    .PARAMETER SourceEnvironmentId
        Environment Id of the source environment that you want to utilized as the baseline for the compare
         
    .PARAMETER DestinationEnvironmentId
        Environment Id of the destination environment that you want to validate against the baseline (source)
         
    .PARAMETER ShowDiffOnly
        Instruct the cmdlet to only output the differences that are not aligned between the source and destination
         
    .PARAMETER IncludeAppIds
        Instruct the cmdlet to also include the users with the ApplicationId property filled
         
    .PARAMETER AsExcelOutput
        Instruct the cmdlet to output all details directly to an Excel file
         
        This makes it easier to deep dive into all the details returned from the API, and makes it possible for the user to persist the current state
         
    .EXAMPLE
        PS C:\> Compare-BapEnvironmentD365App -SourceEnvironmentId eec2c11a-a4c7-4e1d-b8ed-f62acc9c74c6 -DestinationEnvironmentId 32c6b196-ef52-4c43-93cf-6ecba51e6aa1
         
        This will get all system users from the Source Environment.
        It will iterate over all of them, and validate against the Destination Environment.
        It will exclude those with ApplicationId filled.
         
        Sample output:
        Email Name AppId SourceId DestinationId
        ----- ---- ----- -------- -------------

        This will get all system users from the Source Environment.
        It will iterate over all of them, and validate against the Destination Environment.
        It will include those with ApplicationId filled.
        It will only output the users that is missing in the destionation environment.
