Added a WIP array.mean() implementation.
mean() now returning correct dtype (int family => float64 return)
WS cleanup.
Comment Spelling Fix
Array reductions tests are now generative and extensible.
Added myself.

WIP Added non-generative basic tests for array reductions.
Working implementation and tests across py2/py3.
Less gorpy.  Tests passed in py2 and py3.
Added min()/max()/argmin()/argmax().
Fix function generative testing. Fixed testing of float64 returns to allclose.
Added reductions branch to testing.
