Mahjong programming tests

Every programmer who has previously tackled attempting to test and verify the veracity of his functions should at one point have attempted to run a set of tests.

Shanten tests

The following tests should work and provide results with an ever decreasing shanten, until a block change occurs. The tests below should provide a series of tests where the shanten count goes down from 6 to 0 three times, -1 _____ times and 0 _____ times.

Currently (2015.04.11@1830 UTC): 6,5,4,3,2,1,0,6,5,4,3,2,1,0,6,5,6.

Tile formats are offered in string arrays and MPSZ format.
