Use this function during module import to create shortcuts for typenames users can be expected to interact with directly. .PARAMETER AliasName The short and useful alias for the type. .PARAMETER TypeName The full name of the type. Example: 'System.IO.FileInfo' .PARAMETER Mapping A hashtable of alias to typename mappings.
