operator() public static method

Used to multiply 2 Quaternions together.

Quaternion multiplication is not communative in most cases. i.e. p*q != q*p

public static operator ( ) : Quaternion
return	Quaternion

		public static Quaternion operator *( Quaternion left, Quaternion right )
		{
			Quaternion q = new Quaternion();

			q.w = left.w * right.w - left.x * right.x - left.y * right.y - left.z * right.z;
			q.x = left.w * right.x + left.x * right.w + left.y * right.z - left.z * right.y;
			q.y = left.w * right.y + left.y * right.w + left.z * right.x - left.x * right.z;
			q.z = left.w * right.z + left.z * right.w + left.x * right.y - left.y * right.x;
