GeoOptimalDemo:
% Simulate a geocentric locally optimal trajectory using the control laws
developed in McInnes to maximize the increase in orbital energy and
replicate Fig. 4.31 and 4.32 from the reference.
Demonstrates PlanetOptimalTraj and GeoOptimalMission.
This demo will first plot the optimal pitch angle as a function of flight
path angle. This will also be shown superimposed on a circular orbit.
Then the trajectory is simulated for 3 and 30 days and the resulting
spirals are plotted.
Since version 7.
