// Abstract Class from which sprites may be derived.
// This basically provides basic variables to hold location and
// the necessary methods to access the location instance variables.
// For basic funtionality, -move: and -renderAt::move: need to be overridden
// -move: should set up px and py to tell the object which way to move
// and renderAt::move: should be able to draw a representation of the
// GameActor. Note that actual movement happens when -moveOneFrame is
// called; -renderAt::move: will call -moveOneFrame if move:YES is chosen.
