note that these routines return 0.0 if no values exist in the X[] which is not "correct", but it is useful so I don't generate NaN in my output

Compute the sample (unbiased estimator) standard deviation following:
Computing Deviations: Standard Accuracy Tony F. Chan and John Gregg Lewis Stanford University Communications of ACM September 1979 of Volume 22 the ACM Number 9
The "two-pass" method from the paper; supposed to have better numerical properties than the textbook summation/sqrt. To me this looks like the textbook method, but I ain't no numerical methods guy.
