// Compute times of moonrise and moonset at a specified latitude and longitude.
//
// This software minimizes computational work by performing the full calculation
// of the lunar position three times, at the beginning, middle, and end of the
// period of interest. Three point interpolation is used to predict the position
// for each hour, and the arithmetic mean is used to predict the half-hour positions.
//
// The full computational burden is negligible on modern computers, but the
// algorithm is effective and still useful for small embedded systems.
//
// This software was originally adapted to javascript by Stephen R. Schmitt
// from a BASIC program from the 'Astronomical Computing' column of Sky & Telescope,
// April 1989, page 78.

// Subsequently adapted from Stephen R. Schmitt's javascript to c++ for the Arduino
// by Cyrus Rahman.
