Implementation of 1st algorithm for reducing Readings

This algorithm was provided by Robert Ashenfelter based in part on the work of Ralph Bucher in his paper "Exact Solution for Three Dimensional Hyperbolic Positioning Algorithm and Synthesizable VHDL Model for Hardware Implementation".

Neither Ashenfelter nor Bucher provide any guarantee as to the intellectual property status of this algorithm. Use it at your own risk.
