* Difference in variance calculations between Excel/Gnumeric and Open/LibreOffice
* Simplify STDEV() function logic by remembering that STDEV() is simply the square root of VAR(), so we can simply use the VAR() calculaion rather than duplicating the basic logic... and also allow for the differences between Excel/Gnumeric and Open/LibreOffice
* Start splitting some of the basic Statistical functions out into separate classes containing just a few similar functions
* Splitting some of the basic Statistical functions out into separate classes containing just a few similar functions - MAX(), MAXA(), MIN() and MINA()
* Splitting some more of the basic Statistical functions out into separate classes containing just a few similar functions - StandardDeviations and Variances
