Multiple reference importer script
The main feature is to reference any number of different files as many times as you want at once.
The second feature allows user to add these files under groups and namespaces.
The namespace and the group names can be the same name for all or different name for each file.
The script is very helpful with crowd scenes in Maya and with any layout scenes that may have multiple assets used as a reference.
