Set up window in Phoenix Client

[apachano]

Everything the client does happens inside a window. One of the first things the client's main thread needs to do is create this window. If all the window does is exist or output cout then that satisfies this requirement but the design should be focused on being able to implement the world into it next.

Not sure exactly how this is done but in the client I am imaging we do something like:

Window window = Window();
window.run();

Where Window is implemented inside Quartz.
