Function: Evac(Player, X, Y, Z, Heading)

Description: Evacuates the Player (optional field) or their group (No fields) to a safe spot, typically the zone’s designated evacuation point (e.g., the zone entrance). This mimics the effect of an evac spell.

	Y: Float - Optional Y Coordinate (must supply X,Y,Z,Heading).  If for group set Player to nil.
	Z: Float - Optional Z Coordinate (must supply X,Y,Z,Heading).  If for group set Player to nil.
	Heading: Float - Optional Heading Coordinate (must supply X,Y,Z,Heading).  If for group set Player to nil.
	
Returns: None.

    Evac()
end
