CountDict
A counter class for memoized values stored in a dictionary, with
keys based on the method's input arguments.
A CountDict object is instantiated in a class for each of the
class's methods that memoizes its return value in a dictionary,
indexed by some key that can be computed from one or more of
its input arguments.
We expect that the metaclass initialization will fill in the
.underlying_method attribute with the method that we're wrapping.
We then call the underlying_method method after counting whether the
computed key value is already present in the memoization dictionary
(a hit) or not (a miss).
