Tests: disable de-CH related number format tests because of Win 8.1 bug
Added RSquared class (and test - in TD like you mean it style) to the project.
Added license comments to file.
GoodnessOfFit: benchmarking indicates pearson correlation is twice as fast
Distance: add Pearson's distance
GoodnessOfFit: docs, add R value
Statistics: comment in Correlation.Person on robustness
Correlation: optimize Spearman ranked correlation algorithm #171
Distance: add Canberra distance
Distance: add Minkowski distance (generalized p-norm)
