Coyote/points controller

* Adding infrastructure, such as gems (paranoia) and rspec (& rspec_rails)
* Basic point API functionality (for this see the [commit message](https://github.com/coyote/datacultures/commit/bd72419ce2049cc78414cd8f5f64ada4687d826e "Add point logic"))

The [second line of spec/spec_helper.rb](https://github.com/coyote/datacultures/blob/coyote/points_controller/spec/spec_helper.rb#L2 "Include for factory_girl") might need to later become just "include 'factory_girl', but for now the least amount needed is included. 
@christianv I will look into this too.
