<VV> Thermister testing

[Geoffrey A Johnson]

Thats the way.  There is a chart of resistance that Matt Nall has on his 
webpages to compare to.  Although no poweer source needed, just measure 
the resistance at various temps.  Of the dozen or so thermisters I have 
tested, all fell remarkably close to the chart.
