% Computes a gravity gradient torque.
Since version 1.
--------------------------------------------------------------------------
Form:
t = TGG( inr, u, wO )
--------------------------------------------------------------------------
------
Inputs
------
inr (3,3) Inertia matrix
u (3,:) Unit vector from the earth to the spacecraft
in the spacecraft body frame (the same frame as
the inertia matrix.)
wO (1,1) Orbit rate (rad/sec)
-------
Outputs
-------
t (3,:) Torque (units will be consistent with inertia)
