Work on the framework, BEGINS!

Removed setting of headers within the main "index.php", let it be governed from within the view.

Added a new Controller and Model class for "Currency". Used a FREE API to allow us to convert currencies.
Usage: <base URL>/?q=currency/convert/<from>/<to>/<opt:amount>

Added a JSON view to render the $data returned from Model in a JSON string. Good for making an API!

That's all! More to come!
