removed the now-obsolete 'fast' option from ccdf bw selection routine.
interim commit - working on cpdf ls (np.c)
tweaked how the cpdf ml routine handles nans and infs caused by zero
densities
new cpdf routine
still a bit glitched :)
debugged :)
added partial tree search support to kernel_weighted_sum_np
still working on tree support for conditional density ls cv
partway through overhauling the parallelization of cpdf ls
both dimension + index-restricted tree searches implemented
trees + ls cpdf broken :)
ls cpdf cv + trees working, and the results are in: it's very, very fast.
Still not done optimizing, need to add an extra tree search to hit that nlog^2(n) scaling
