/**
* Least Squares Best Fit By Roxy and Ed Williams

* This algorythm is high speed and has a very small code footprint.
* Its results are identical to both the Iterative Least Squares published
* earlier by Roxy and the QR_SOLVE solution. If used in place of QR_SOLVE
* it saves roughly 10KB of program memory.
