refined the "smart" behavior in nrrdHistoEq(), so that the regular map generated from the histogram integral increases smoothly past the bins that were ignored, instead of staying flat.  Noticed this problem when doing smart heq on scatter plots with many pixels that had value 1: these were being mapped to 0 instead of something non-zero.
