// Title: Entrypoint 

//  Macro: ENTRYPOINT
//  A macro which is used to specify the class containing the entrypoint.
//  For example, if the class PongGame is the class derived from <Application>
//  which implements main, in the file defining PongGame it is important to
//  include ENTRYPOINT(PongGame) so that the entry point becomes PongGame::main.
