Revision 19

Add Support for:
** writing granny2 data to a new or existing file
   -- the way this is setup, is that if we only a change a few things
	and update that data in the root granny_file_info; then all
	existing unchanged data present in the granny_file_info will
	be written out as well.
	This way we can add support to edit data in a piece-milled fashion.
