-- JS: I changed the way file storage uses the CR:  cr_items will store
-- JS: a file's meta-data, while cr_revisions will store specifics of a
-- JS: file's version.  Every file has at least one version.
-- JS:
-- JS: 1) The name attribute in cr_items will store the "title" of the 
-- JS:     of the file, and all its versions. 
-- JS:
-- JS: 2) The title attribute in cr_revisions  will store the filename 
-- JS: of each version, which may be different among versions of the same title.
-- JS:
-- JS: 3)   Version notes will still be stored in the description attribute. 
-- JS:
-- JS: The unfortunate result is that the use of "title" and "name" in 
-- JS: cr_revisions and cr_items, respectively, are interchanged.
