Made this change so that HMMWeka runs for numeric data. What was there before did not make sense at all. Now it makes some sort of sense, but I do not really understand what this method is supposed to do. This class was originally in the pace regression package and should really have stayed there. I do not think it is fit for general consumption. This also holds for the FloatingPointFormat class.
