Check Player equality

It is possible to test for player equality using ==:

>>> import axelrod as axl
>>> p1, p2, p3 = axl.Alternator(), axl.Alternator(), axl.TitForTat()
>>> p1 == p2
True
>>> p1 == p3
False

Note that this checks all the attributes of an instance:

>>> p1.name = "John Nash"
>>> p1 == p2
False

This however does not check if the players will behave in the same way. For example here are two equivalent players:

>>> p1 = axl.Alternator()
>>> p2 = axl.Cycler("CD")
>>> p1 == p2
False

To check if player strategies are equivalent you can use :ref:`fingerprinting`.
