parse/parse_c:

parse/parse_c:
    -python_output will be called from the parser. Once we have
     each method implemented we have a working C++ parser
    -Add BBHandler. It will parse .bbclass, .inc and .bb files
     for us and calls into c (if speed critical we might remove
     that fascade)
    -make scanner get FILE* and PyObject* as input
    -make parser call python_output with lex_t
    -bitbakescanner.cc,bitbakeparser.cc update generated code

    -Parsing flow:
    parse -> handle -> parse_c.BBHandler -> parse_c.C -> lex
    -> (lemon *-> python_output) ... return
