/* Spectrometer/Colorimeter color spot reader utility */

* Author: Graeme W. Gill

/* This program reads a spot reflection/transmission/emission value using */
/* a spectrometer or colorimeter. */
/* TTBD
*
* Add a "w" command to set & then display L*a*b* relative to that white.
*
* Add option to automatically read continuously, until stopped. (A bit like -O)
*
* Make -V average the spectrum too (if present), and allow it to
* be saved to a .sp file.
*
* Should fix plot so that it is a separate object running its own thread,
* so that it can be sent a graph without needing to be clicked in all the time.
*
* Should add option for Y u' v' values.
