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.

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
