v1.2 Release

Essentially thermistor_interpolator is now where it should have been before I released v1.1:

1. More and improved checks on calculation results throughout the routine
2. End-to-end accuracy test of new operational mode (NTC defined by .csv file of temperatures /resistances) passed
3. Removed some latent debug code...

Other minor touchups:

1. Passing iterator arguments by const reference instead of value in iterator-based GCD() and LCM() variants
2. Use of type aliases to make RCSn less unreadable

v1.1 Release

A modest update release:

1. Fully specialized template functions are inlined as they should have been all along.
2. thermistor_interpolator permits nominal NTC thermistor characteristics to be defined by resistance at nominal temperature and ß coefficient or by a table of temperature and resistance values supplied as a .csv file.
3. The GCD and LCM routines have proper test code and are specified in two-argument and multiple argument variations.
4. RCSn has a more generic interface.

v1.0 Release

Deciding to cut a release. The test routines in the integer/ and statistics/ directories are fairly thorough, and I have received a report of a successful outcome with the thermistor interpolator from a user who performed some unit testing and bench qualification.
