SubOrbMaxRange:

--------------------------------------------------------------------------
   Computes maximum range for a sub-orbital traj. given initial velocity.
   Also returns the initial flight path angle required to reach the max
   range.

   Assumes spherical Earth and initial / final altitudes of zero.
   Since version 1.0
--------------------------------------------------------------------------
   Form:
   [maxRange,gammaOpt] = SubOrbMaxRange( V );

   ------
   Inputs
   ------
   V           (1,N)   Initial velocity (km/s)
                       

   -------
   Outputs
   -------
   maxRange    (1,N)   Maximum range around the Earth (km)
   gammaOpt    (1,N)   Optimal flight path angle to reach max range (rad)
