Would we then also want to move the export and import views out to their own app?  It just seems this is pretty tightly related to those functions, as eventually we may want to be able to export and import formats other than xml as well. Should I maybe just add the view to the existing import_export.py and put the "export_to_git" function in there as well, or maybe move that function into the modulestore lib somewhere around export_to_xml?
