Detailed Description

Simple class for measuring certain statistics dynamically that is numerically efficient.

This code is based off of similar class written by John D. Cook http://www.johndcook.com/standard_deviation.html

Which is based on the following references: Chan, Tony F.; Golub, Gene H.; LeVeque, Randall J. (1983). Algorithms for Computing the Sample Variance: Analysis and Recommendations. The American Statistician 37, 242-247.

Ling, Robert F. (1974). Comparison of Several Algorithms for Computing Sample Means and Variances. Journal of the American Statistical Association, Vol. 69, No. 348, 859-866.
