+			<UserDocu>
+				A Rotation using a quaternion.
+				The Rotation object can be created by:
+				-- an empty parameter list
+				-- a Rotation object
+				-- a Vector (axis) and a float (angle)
+				-- two Vectors (rotation from/to vector)
+				-- three floats (Euler angles) as yaw-pitch-roll
+				-- four floats (Quaternion) where the quaternion is specified as:
+				   q=xi+yj+zk+w, i.e. the last parameter is the real part
