// IcarusInterface.h: ICARUS Interface header file.
// -Date: ~October, 2002
// -Created by: Mike Crowns and Aurelio Reis.
// -Description: The new interface between a Game Engine and the Icarus Scripting Language.
// An Interface is an Abstract Base Class with pure virtual members that MUST be implemented
// in order for the compile to succeed. Because of this, all needed functionality can be
// added without compromising other core systems.
// -Usage: To use the new Icarus Interface, two classes must be derived. The first is the
// actual Icarus Interface class which contains all relevent functionality to the scripting
// system. The second is the Game Interface which is very much more broad and thus implemented
// by the user. Icarus functions by calling the Game Interface to do certain tasks for it. This
// is why the Game Interface is required to have certain functions implemented.
// The basic Icarus Interface ABC.

// Description: The Game Interface is used by the Icarus Interface to access specific
// data or initiate certain things within the engine being used. It is made to be
// as generic as possible to allow any engine to derive it's own interface for use.
