added parabola search to bisection
made a stupid mistake in parabola solver
parabolize using only the three smallest points found
include origin in the parabola data set
move center if need be (in bisection)
added length scaling to simplex search in find_global_minimum
a lot of silly diagnostics
added calculate_gradient method to aps class
try a gradient search at the end of bisection, rather than a parabola search
a diagnostic statement
playing around with gradient
some changes that make resume work
removed gradient search; now need to implement what I learned about simplex from astro lab; namely -- randomly rotate each pt separately; rotate about mindex; make sure that you normalize the position of the rotation center
removed junk code from find_global_minimum to make room for the rotation, etc.
simplex search applies random kick and rotation if sig gets too small
