Okay, I've made the changes Tim suggested, plus corrected a couple of
bugs
(it was trying to display scientific notation and I wasn't allowing it,
so
I was losing the exponent!), please let me know if there are any
problems.
By default, the program assumes a DT-Fusion drive (not the best for
interplanetary travel, mind you) and returns values for true anomaly for
the planets on 9 March 2063 (note: these numbers are corrected from my
last post).  When you change either the origin or the target planet, it
automatically calculates the lowest-energy time (corresponding to a
Hohmann orbit) to that destination.

Oh, btw, I remembered two other terms from last post I should define:

*Perihelion (rp) = distance of closest approach of planet to Sun
*Aphelion (ra)	 = furthest distance of planet from Sun

TTYL..
