set bisection tolerance to 0.01 delta_chisquared
relaxed stopping conditions on Coulomb search
made s_curve modes narrower
updated aps_runner_s_curve.cpp so that it is suitable for running
multiple runs to produce figures for paper
updated s_curve_analyzer for the batch runs

also prints indices of nodes in the diagnostic statements
let nodes recenter if they find a point that is closer to the
geographic center of their range and whose chisq is less than
0.1 delta_chisq above chi_min
recentering had to be done with a buffer
needed to make sure geographicCenter defaulted
simplex now will not start in a box containing the smallest seed
from a previous simplex
simplified that process
added print statement to see how probabilities are distributed when choosing
a box for simplex search
compare box chosen by probability with box chosen by volume only
when picking a box for simplex, for each pixel calculate a probability
that the pixel will lead back to a known node.

This is included in the probability minimization
factored out pold calculation into its own routine
choose search mode based on cpu time; added time penalty
never do focus (just for testing purposes)
test print statements
have to do focus to get sigma for lpold
chose by lpold after choosing by lpbad
choose on pBad
then choose on pOld
then choose on distance to nodes
