<#
    .SYNOPSIS
        Get users from environment
         
    .DESCRIPTION
        Enables the user to fetch all users from the environment
         
        Utilizes the built-in "systemusers" OData entity
         
        Allows the user to include all users, based on those who has the ApplicationId property filled
         
    .PARAMETER EnvironmentId
        The id of the environment that you want to work against
         
        This can be obtained from the Get-BapEnvironment cmdlet
         
    .PARAMETER IncludeAppIds
        Instruct the cmdlet to include all users that are available from the "systemusers" OData Entity
         
        Simply includes those who has 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:\> Get-BapEnvironmentUser -EnvironmentId eec2c11a-a4c7-4e1d-b8ed-f62acc9c74c6
         
        This will fetch all oridinary users from the environment.
         
        Sample output:
        Email Name AppId Systemuserid
        ----- ---- ----- ------------
