/**

*

*	GEStatus 

*	Derived from IGene , which can be treat as a complex state. enter state when attach to its host, leave state when detach to it.

*	Yes, an GEStatus is a complex state model for unit in combat, a unit in combat can have one or more GEStatus at the same time, which

*	mean that the unit is in these parallel state, and the unit is the state host.

*

*	Complex State is a combination of simple, mutable state, like the move state in Entity will have 3 simple , mutable state: 

*	state Moving:		unit is moving

*	state Idle:			unit is stand by and ready to move

*	state Freeze:		unit is frozen and can't be moved

*	And a unit in combat will have the following simple, mutable state:

*	state Peace:		no combat

*	state Ready:		in combat, ready for casting a spell to its target

*	state Casting:		in combat, casting a spell on its target

*	state CoolDown:		in combat, cool down time interval just after a previous spell is casted

*	state Forbidden:	in combat, forbidden to cast a spell

*	state Charging:		in combat, approaching to its target for casting a spell

*	And so on...
