Updating Gemfile to specify Postgress; rebuilt bundle to update Gemfile.lock.
Adding basic models for a recipe (recipe, ingredients, directions).

Adding recipes_controller; includes hash of test data, if I can ever get it to save to DB....

Adding root-level route. (Currently routes root to recipes#index; this will change eventually.)

Modified database.yml to point to local dev DB.

Built basic recipes/index.html.erb to print out a successfully retrieved recipe.
