Fixes for Dendrogram_Num, Genus, etc...

*  Dendrogram_Num can optionally fit the last 20% of usable data (which is the area of interest) instead of using knots from a spline.
* Genus distance uses splines with no smoothing to avoid instable solutions
*  Updates for MPI
*  Extra columns in csv outputs for Fiducial/Design numbering
*  Updates to plotting functions
