Xaml Loader

Until now, we have been processing XAML on the server and delivering JSON to the client.  When we first did this, we knew it would be a quick and dirty implementation to test out the engine.  I have spent the last week building a Xaml Loader on the client.  In addition to removing much of the server pieces, I have been creating many unit tests to stabilize this new work.  Hopefully the next update will deliver news of speed improvements.
