This patch removes all superfluous files from the directory, especially the
binary files in the doc folder. They are still available in the git
repository http://github.com/daherb/GF-latin which is still the main
repository for the development of the latin grammar.
The GF files are updated to a state close to the one at the end of the GF
Summer School 2015 where they were extended to support the MUSTE grammar.
While the abstract Numeral inherits only Cat[Numeral,Digits], some of the
concrete NumeralNNN of Numeral inherited everything from CatNNN.
Normally the compiler outputs a warning message when a concrete syntax
contains superflous lincats, but apparently not when they get included
through inheritance...
This does not seem to cause problems in the Haskell run-time system, but the
C run-time system fails to load PGFs with superflous lincats.
This problems shows up when creating application grammars that inherit Numeral.
The Phrasebook is an example of such a grammar.
