function Rename-TNGroup {
    <#
    .SYNOPSIS
        Renames a list of groups
 
    .DESCRIPTION
        Renames a list of groups
 
    .PARAMETER SessionObject
        Optional parameter to force using specific SessionObjects. By default, each command will connect to all connected servers that have been connected to using Connect-TNServer
 
    .PARAMETER GroupId
        The ID of the target group
 
    .PARAMETER Name
        The name of the target group
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with 'sea of red' exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this 'nice by default' feature off and enables you to catch exceptions with your own try/catch.
