+CMS: Add feature to allow exporting a course to a git repository by

 Studo: Fix import/export bug with conditional modules. STUD-149
 
 Blades: Persist student progress in video. BLD-385.

+"""
+This command exports a course from CMS to a git repository.
+It takes as arguments the course id to export (i.e MITx/999/2020 ) and
+the repository to commit too.  It takes username as an option for identifying
+the commit, as well as a directory path to place the git repository.
+
+By default it will use settings.GIT_REPO_EXPORT_DIR/repo_name as the cloned
+directory.  It is branch aware, but will reset all local changes to the
+repository before attempting to export the XML, add, and commit changes if
+any have taken place.
+
+This functionality is also available as an export view in studio if the giturl
+attribute is set and the FEATURE['ENABLE_PUSH_TO_LMS'] is set.
