Don Cross cc6a32bb98 Include the gravsim check in the unit tests. ...

I have gravsim_test.c to the point where it calculates a
standard deviation of error between TOP2013 and Astronomy Engine
for calculating the position of Pluto over 10 worst-case samples.
My baseline is now 0.205303 arcminutes of heliocentric position error.

For Runge-Kutta (or some other method) to be an improvement, it
has to beat that score without incurring significant extra work
or larger memory consumption.
