Add grammar.py for generating compiler-compilers
...
grammar.py is meant as a compiler compiler compiler, taking in a grammar
structure and returning flex and bison files. It can also parse EBNF.
Currently there are still remnants of VHDL-specific stuff in the code,
because parsing VHDL was what it was initially about.
