File: MyController.h

Abstract: Interface for the MyController class. This class performs
program initialization and responds to the program user interface (UI). 
At startup it will create an OpenGL context and Core Video display link 
which will be used to drive screen capture. It is responsible for initiating
actual screen capture based on the user selection (for the type of capture).
