Include .gitignore and remove all bin/obj files
Set up shell. The shell window is the top-level window of an application
based on the Prism Library. This window is a place to host different UI
components that exposes a way for itself to be dynamically populated by
others, and it may also contain common UI elements, such as menus and
toolbars. The shell window sets the overall appearance of the application.
Added region in shell so view could be adding in dynamically later
Added Bootstrapper, responsibile for the initialization of an application
built using Prism Library
