        * many files: Moved data_structure, document, and part of python_embed directories
        into libglom, so that the glom python module does not need to use symbols in the
        glom executable, because this is not allowed in cygwin, using --no-undefined.
        In future, this can be used as public API to make the document/database structure
        available to separate utilities and a web UI.
