Add class def in addition to MRO

[Jackson]

# pycg/processing/cgprocessor.py
...
if pointer_def.get_type() == utils.constants.CLS_DEF:

    # Class def
    self.call_graph.add_edge(self.current_method, pointer)
...

For our purposes we would also want the class itself. Would it be possible to add the option to include it as an edge in the config?
