Path: Orbit/StraightLine

% Compute straight line bang-bang trajectory with constant thrust
 Compute the switch time as a function of thrust, exhaust velocity, initial
 mass, and flight time. Can account for an initial velocity v0. 

 Type StraightLineConstantThrust for a demo.
   [d,dF] = StraightLineConstantThrust( d0 )

   d0    	(.)   Data structure
                 See StraightLineDataStructure
    if engine mass mE is empty, it can be computed from these fields:
             .thrust (1,1) Thrust, N
             .sigma  (1,1) Engine specific power, W/kg
             .eta    (1,1) Efficiency, power to thrust

   d     	(.)   Data structure with updated fields
                 .p   Power
                 .mF  Fuel mass
                 .mE  Engine mass
                 .mD  Dry mass
                 .m0  Initial mass
                 .tS  Switch time
                 .vS  Switch velocity
                 .dF  Final distance
                 See StraightLineDataStructure
   dF     (1,1)  Distance achieved
