Figured out how to test the project without exposing deps that we want to mock. #n00b :P

Begun using the magical proxyquire (along with the usual sinon, chai, mocha combo) to mock out module deps without having to faff around with any rewiring jazz. :heart:
Written up a first test as a proof of concept. Full tests to follow!
Added first basic tests, and the awesome-o proxyquire for deps [also usual sinon chai mocha parade :)]. Now yoga :P
