// DESCRIPTION:
// Base class for all enities that are controlled by Sin.  If you have any
// object that should be called on a periodic basis and it is not an entity,
// then you have to have an dummy entity that calls it.
//
// An entity in Sin is any object that is not part of the world.  Any non-world
// object that is visible in Sin is an entity, although it is not required that
// all entities be visible to the player.  Some objects are basically just virtual
// constructs that act as an instigator of certain actions, for example, some 
// triggers are invisible and cannot be touched, but when activated by other
// objects can cause things to happen.
//
// All entities are capable of receiving messages from Sin or from other entities.
// Messages received by an entity may be ignored, passed on to their superclass,
// or acted upon by the entity itself.  The programmer must decide on the proper
// action for the entity to take to any message.  There will be many messages
// that are completely irrelevant to an entity and should be ignored.  Some messages
// may require certain states to exist and if they are received by an entity when
// it these states don't exist may indicate a logic error on the part of the 
// programmer or map designer and should be reported as warnings (if the problem is
// not severe enough for the game to be halted) or as errors (if the problem should 
// not be ignored at any cost).
