Created form for answer submission.
Wrote ajax for form submission. It's my first time using CoffeeScript, please be gentle.
Created views to render questions and answers.
Changed route for cards#answer. This now allows the deck id and card id to be sent through the post action.
wip.

The form's route won't change if I use a separate method to send the form because it doesn't rerender when it submits. If the form is reloaded with the question, then JavaScript doesn't recognize it because the form was created after the JavaScript already loaded.
