This lib is supposed to be used as a sensor's calibration or control program. This makes Cubic Spline Model from some sample plots(sets of (value, voltage)), and then discretize the model (dividing the range of voltage into some steps) in order to use the calibrated model data without getting the INVERSE function.

aktk 2:40ae18445079 7 * - This library is for providing a distance from TRP105F, photo-reflect proximity sensor,
aktk 0:e85788b14028 8 * to whatever reflect the flash.
aktk 2:40ae18445079 9 * - Deistance is derived as a voltage signal of TRP105F.
aktk 0:e85788b14028 10 * - An object of TRPFS class has an array of sets of
aktk 0:e85788b14028 11 * distance(16 bit-value) and voltage(16bit-value) at the distance.
aktk 2:40ae18445079 12 * - The range of distances that an array has in sets is [0:255] by 1.
aktk 2:40ae18445079 13 * - an array is derived from a cubic spline curve model.
aktk 0:e85788b14028 14 * - In order to derive spline curve, some value sets should be got
aktk 0:e85788b14028 15 * at the first calibration.
