/*
    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.
