void sio2PhysicAddObject	(	SIO2physic *	_SIO2physic,
		SIO2object *	_SIO2object
	)

Add a new physic body to the SIO2physic world. Depending on the type of physic object that we are planning to add to the physic world, this function will analyze the _SIO2object->flags to determine which type of physic object we are trying to add and will dispatch the SIO2object to the appropriate function.
