incremented development version number
Fixed a bug in LocalAnalysis that caused multiwavelength images not to be split unless the parameter was explicitly specified.  Fixes #47.
changed local maximum separability thresholding filter to detect all maxima and take the two largest for fitting to avoid situations where very low broad maxima would go undetected.  Fixes #54.
Moved label filter application at end of filter outside of conditional to make sure regions are always relabeled.  Otherwise, this could lead to now unconnected regions having the same label in some cases.  Fixes #50.
added toString method for human-readable histogram formatting
added optional parameter to control number of recursions in recursive thresholding
Fixed a bug in the label filter where regions were only mapped one level deep in some places.  Fixes #50 (really, I swear...).
