Population class extension: cache module

File containing the class extension for the population object that contains cache functionality

Module containing (e.g. LRU) cache functionality for binary_c-python.

We use cachetools when possible because this allows us to set up the cache of the appropriate size for the task in the population_options dict. Please see the LRU_* options in there.
