% fmincon solution for a trajectory between two planets
 Generates a trajectory plot. Uses the JPL ephemerides. planet2 can be
 a number from 1-9 or a data structure

 This stops at the target.

 Type TrajectoryBetweenTwoPlanets for a demo using both JPL 
 ephemerides and a data structure for planet2.
   s = TrajectoryBetweenTwoPlanets( jD0, planet1, planet2, years, n, opts, nRSim )

   jD0       (1,1)  Start Julian Date
   planet1   (1,1)  Id of departure planet (1-9)
   planet2  	(1,1)  Id of arrival planet (1-9) or data structure
                    .name (1,:) Name
                    .el   (1,6) Orbital elements - epoch must be jD0
   years   	(1,1)  Mission duration (years)
   n         (1,1)  Number of steps in solution
   opts     	(.)    Data structure for fmincon
   nRSim     (1,1)  Ratio of sim points to optimization points

   s         (.)   Output structure      
                   .x    (6,:)  States
                   .a    (3,:)  Acceleration vector
                   .jD0  (1,:)  Julian date
                   .t    (1,:)  Elapsed time
