Added accessors to Color
Added an initialize phase to the Renderer interface
A Scene is now a user configurable composite surface with essential tracing information like activeCamera, etc.
ApplicationDelegate now initializes the main loop, renderer, and auxiliary controllers
Configuration now supports options for isLeaf, isClock, and masterScene
Launcher now calls down to a SceneLoader to allow for configurable scene loading
Added an interface for Tracers (to abstract out the algorithmic aspects of tracing from the configuration aspects)
