function Get-CCMSoftwareUpdateGroup {
    <#
        .SYNOPSIS
            Get information for the Software Update Groups deployed to a computer, including compliance
        .DESCRIPTION
            Uses CIM to find information for the Software Update Groups deployed to a computer. This includes checking the currently
            reported 'compliance' for a software update group using the CCM_AssignmentCompliance CIM class
        .PARAMETER AssignmentName
            Provide an array of Software Update Group names to query for
        .PARAMETER AssignmentID
            Provide an array of Software Update Group assignemnt ID to query for
        .PARAMETER CimSession
            Computer CimSession(s) which you want to get information for the Software Update Groups
        .PARAMETER ComputerName
            Computer name(s) which you want to get information for the Software Update Groups
        .PARAMETER PSSession
            PSSessions which you want to get information for the Software Update Groups
        .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
            PS C:\> Get-CCMSoftwareUpdateGroup -Computer Testing123
                Will return all info available for the Software Update Groups deployed to Testing123
