21*
22*	GEStatus 
23*	Derived from IGene , which can be treat as a complex state. enter state when attach to its host, leave state when detach to it.
24*	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
25*	mean that the unit is in these parallel state, and the unit is the state host.
26*
27*	Complex State is a combination of simple, mutable state, like the move state in Entity will have 3 simple , mutable state: 
28*	state Moving:		unit is moving
29*	state Idle:			unit is stand by and ready to move
30*	state Freeze:		unit is frozen and can't be moved
31*	And a unit in combat will have the following simple, mutable state:
32*	state Peace:		no combat
33*	state Ready:		in combat, ready for casting a spell to its target
34*	state Casting:		in combat, casting a spell on its target
35*	state CoolDown:		in combat, cool down time interval just after a previous spell is casted
36*	state Forbidden:	in combat, forbidden to cast a spell
37*	state Charging:		in combat, approaching to its target for casting a spell
38*	And so on...
