+Calculate the rotational inertia (Ixx, Ixy, Ixz, Iyy, Iyz, Izz) for a kite model from settings. 
+Modifies the kite model by initializing the masses.
 
 Parameters:
 - X: x-coordinates of the point masses.
 - Y: y-coordinates of the point masses.
 - Z: z-coordinates of the point masses.
 - M: masses of the point masses.
-- `include_kcu`: Include the kcu in the rotational intertia calculation?
+- `include_kcu`: Include the kcu in the rotational inertia calculation?
 - `around_kcu`: Uses the kcu as the rotation point.
