wr (Weighted Random)

wr is a weighted random implementation in Python.

wr.choice can be fed with a mapping (such as dictionaries) containing a returnable (what to return) and a integer representing their respective weight. The key can be anything hashable but the weight must be a integer.

Optionally you may feed wr.choice with a sequence of pairs.
