Removed file_context, name_context, name_schema, and ranks modules
(Moved into KitCAT Project).
Wrote much simpler abx_context to replace essential features for ABX.
After discovering that sub-packages in Blender add-ons don't work (this
seems to be very broken!), I replaced the parsers subpackage with a
parsers.py module (almost as simple as concatenating the source files in
the package). I may be removing this name-parsing system from ABX
entirely, soon, possibly moving it into KitCAT.
Initial commit of ABX development sources. The abx package itself is in the abx folder. The MakeAddOnZip.py script creates the archive to install into Blender in the pkg folder. The tests folder contains unit tests which require the contents of testdata as fixtures.
