add special treatment of Integer variables -> binning chooses as one bin per integer
Fix MethodCategory .. where since about 3years, the re-ordering of variables didn't work anymore (since VariableRearrangeTransform was introduce)
add a ROC-curve calculation tool ... to be used later or otherwise stand-alone (i.e. not in MethodBase)
just comment fixing
get the rest equal between v5 and v6
