midpoint_adaptive_test():
  MATLAB/Octave version 6.4.0
  Test midpoint_adaptive() on several ODE's.

lotka_test():
  midpoint_adaptive() solves lotka_ode().
  A pair of ordinary differential equations for a population
  of predators and prey are solved using midpoint().

  The exact solution shows periodic behavior, with a fixed
  period and amplitude.

  Steady state at r = 5000, f = 2000.
