OPS: reduce memory usage of statistical functions

Many of the statistical functions in the imglib ops function.real package that copy data to a buffer before calculating stats. In many cases this is unnecessary. Improve the memory usage going forward.

In the 'ops-stats' branch I have new memory efficient functions in place. Specifically StatCalculator has changed. All that has to happen now is for the changes to be merged into master.
