LaunchTime:

--------------------------------------------------------------------------
   Compute the time until launch, given launch site and desired orbit.
   Since version 1.0
--------------------------------------------------------------------------
   Form:
   [dT,jD] = LaunchTime( lat, lon, inc, ra, jD0 )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   lat            (1,1)  Latitude of launch site (rad)
   lon            (1,1)  East longitude of launch site (rad)
   inc            (1,1)  Inclination (rad)
   ra             (1,1)  Right ascension (rad)
   jD0            (1,1)  Julian date right now

   -------
   Outputs
   -------
   dT             (1,2)  Time until next launch opportunities (sec)
   jD             (1,2)  Julian date of next launch opportunities
