function Get-CCMClientDirectory {
    <#
        .SYNOPSIS
            Return the MEMCM Client Directory
        .DESCRIPTION
            Checks the registry of the local machine and will return the 'Local SMS Path' property of the 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Client\Configuration\Client Properties'
            registry key. This function uses the Get-CIMRegistryProperty function which uses CIM to query the registry
        .PARAMETER CimSession
            Provides CimSessions to gather the MEMCM Client Directory from
        .PARAMETER ComputerName
            Provides computer names to gather the MEMCM Client Directory from
        .PARAMETER PSSession
            Provides PSSessions to gather the MEMCM Client Directory from
        .PARAMETER ConnectionPreference
            Determines if the 'Get-CCMConnection' function should check for a PSSession, or a CIMSession first when a ComputerName
            is passed to the function. This is ultimately going to result in the function running faster. The typical use case is
            when you are using the pipeline. In the pipeline scenario, the 'ComputerName' parameter is what is passed along the
            pipeline. The 'Get-CCMConnection' function is used to find the available connections, falling back from the preference
            specified in this parameter, to the the alternative (eg. you specify, PSSession, it falls back to CIMSession), and then
            falling back to ComputerName. Keep in mind that the 'ConnectionPreference' also determines what type of connection / command
            the ComputerName parameter is passed to.
        .EXAMPLE
            C:\PS> Get-CCMClientDirectory
                Returns the MEMCM Client Directory for the local computer
        .EXAMPLE
            C:\PS> Get-CCMClientDirectory -ComputerName 'Workstation1234','Workstation4321'
                Returns the MEMCM Client Directory for Workstation1234, and Workstation4321
