[Insight-developers] Incorporating the new statistics framework in ITK

[Bill Lorensen]

Here is a note I sent a while ago:

If Histogram were called MeasurmentHistogram, I might be able to make
a backward compatible itkHistogram that uses the new
MeasurmentHistogram. Currently, the new Histogram has
changed the template arguments from the old. Actually it matches
exactly itkVariableDimensionHistogram, but that is not such a great
name for the new Statistics.
