% Compute dual spin turn rates
Compute range of allowable initial rates for the dual spin turn given a
momentum wheel aligned with pitch and the initial rate about yaw.

Form:
[wIMax, wIMin, wFMax] = DSTCrit( iWheel, iPitch, iRoll, iYaw, hW )
--------------------------------------------------------------------------
------
Inputs
------
iWheel (1,1) Wheel inertia
iPitch (1,1) Pitch axis inertia
iRoll (1,1) Roll axis inertia
iYaw (1,1) Yaw axis inertia
hW (1,1) Final momentum wheel momentum
-------
Outputs
-------
wIMax (1,1) Maximum allowable yaw rate
wIMin (1,1) Minimum allowable yaw rate
wFMax (1,1) Final pitch axis rate
