How many distinct handfuls of 7 may be drawn from a packet containing 4 blue candies, 3 green ones, 3 red, 2 orange and 1 yellow?

The code here provided is a tool to compute the answer to this one and similar questions, both with brute force and with an enumerative combinatorics closed form formula. Theoretical grounds about the closed form computations can be found here: http://arxiv.org/abs/1511.06142 . Use the same link to cite the code.

Based on python 3.5+. All the methods and main_example.py are back compatible with python 2.7. Use python 3 to have optimal performance (see xrange).
