put focus back in; allow bisection even if we find points inside the CL
only bixect if chitrue<global_median
added idea of centers of low chisquared to aps.cpp
use idea of centers in bisection
add any good points found by aps_wide to the list of centers
fixed a bug with that
now aps_focus samples in normalized unit spheres about the centers and chooses the point with the farthest nearest neighbor
did not properly handle the setting of a new center after a simplex search
