Bulk API Loader

Augmented CristianCantoro's process.py script that uploads tasks from
geojson files or databases with osmosis schema. See bulk_process.py. New
script is more OOP and a easier to maintain outside of bulk_process
script.

I was unable to test the uploadTasks method of the mapRouletteChallenge
task. I received a 405 status response from the dev server. Would like
assistance with debugging.

I also created this 'test unit' python file of statements I used to test
classes & methods.
