StreamingStatisticsVariance(IEnumerableDouble) Method

Estimates the unbiased population variance from the provided samples as enumerable sequence, in a single pass without memoization. On a dataset of size N will use an N-1 normalizer (Bessel's correction). Returns NaN if data has less than two entries or if any entry is NaN.
