Use custom matches

The Moran process supports custom match classes. Below creates a new class of a match where both players end with a score of 2:

>>> import axelrod as axl
>>> class MassBaseMatch(axl.Match):
...     """Axelrod Match object with a modified final score function to enable mass to influence the final score as a multiplier"""
...     def final_score_per_turn(self):
...         return 2, 2

We then create a Moran process with the custom match class by passing our custom MassBaseMatch to the Moran process with the match_class keyword argument:

>>> players = [axl.Cooperator(), axl.Defector(), axl.TitForTat(), axl.Grudger()]
>>> mp = axl.MoranProcess(players=players, match_class=MassBaseMatch, seed=0)
>>> population =
>>> print(mp.winning_strategy_name)
