	Description:
	Play set of ambient animations on given unit.

	Remarks:
	* Can handle several different anims and auto-switching between them.
	* Detects nearby units with the same animation set and tries to select different animations.
	* A game logic is created on units position and animated unit is then attached to it, to prevent possible problems, like player pushing units around.
	* The unit can be snapped to a set snappoint to prevent game from repositioning the unit.
		* The snappoint is automatically detected, snap distance is 2 meters (in top-down view, ignoring vertical info).
		* To position unit vertically, move its snappoint up/down.
		* A snappoint is a (cyan colored) helper "Sign_Pointer_Cyan_F".
		* This is extremely handy if the unit needs to be placed near object(s) - like on chair near a table.

	3: OBJECT 	- object unit to snap to; function won't try to search for the closest snappoint and will use this snappoint instead
	4: BOOL		- function will try to interpolate into the ambient animation, if the interpolateTo link exists
			- it is not officialy supported, so it's disabled by default
			- works only for transitions from (some) default A3 stances to sets "STAND", "SIT_LOW" and "KNEEL"
