Tim O'Brien 57b9151881 An implementation of ordinary least squares regression with one independent
variable. The implementation uses running sums and does not require the data
to be stored in memory.  Since I could not conceive of any significantly
different implementation strategies that did not amount to just improving
efficiency or numerical accuracy of what I am submitting, I did not abstract
the interface.

The test cases validate the computations against NIST reference data and
verified computations. The slope, intercept, their standard errors and
r-square estimates are accurate to within 10E-12 against the reference data
set.  MSE and other ANOVA stats are good at least to within 10E-8. -- Phil S.
