Added skew function that is based on the sample skew functions provided by Excel and suggested by Wikipedia.
Old modeskew function now points to npskew for "non-parametric skew" as a stepping stone for deprecation. I did not update the profile or summary methods (which manually calculate non-parametric skew but call it modeskew), since I'm not certain what the deprecation plan is.
