AirshipInit:

--------------------------------------------------------------------------
   Initialize an aircraft data structure and state for airship simulation
--------------------------------------------------------------------------
   Form:
   [d,x] = AirshipInit( d, latLonAlt, vAB, eul, trim, wind );
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   d              (.)    Initial aircraft data structure, generated from
                          "BuildAirshipModel", or you may supply just the
                          name of an airship model.
   latLonAlt     (4,1)   Latitude (deg), Longitude (deg), Altitude (km),
                          4th element is Julian Date (default is JD2000)
   vAB           (3,1)   Velocity (m/s), alpha (rad), beta (rad)
   eul           (3,1)   Roll, Pitch, Yaw (rad)
   trim           (1)    Indicates whether to trim (1) or not (0). 
                          (default is 1) 
   wind           (.)    Wind data structure. See "WindModel.m". Optional. 

   -------
   Outputs
   -------
   d              (.)    Aircraft data structure, updated with state 
                          information and trim controls (if desired)
   x              (.)    Initial aircraft state, class "acstate"
