Changed applicable use of `char *` declarations that are passed into

Browse source 
PyArg_ParseTuple() to ``const char *`` to match the recommendation made in
section 1.3 and to support better coding habits.

example were not touched since it is stems from an accredited source and thus
did not want to step on anyone's toes.
