//  Lines beginning with // like this one are interpreted as comments (ignored) by the GADD program
//  so this is a faithful copy of a functional script.
//  I'll explain a couple of the less obvious keywords used above.
//  seq=125 means the measurement will be made (in this case) at 10, 20, 50, 100, 200, 500, ... 10kHz
//  multiplier=10 means decades, in this case .01, .1, 1, 10, 100, 1000, 10000
//  There are more commands.  Another common one is 'set' as in
//     set temperature=100   or set freq=1000
//  and 'wait' gets some use as in
//     wait sec=5   or   wait insert_sample_now
//  the second one of which will pause GADD, 
//  popup a small window with the insert message and wait until you click it.
//  But the language is pretty simple, mostly it's set and sweep
//  BTW, the temperature settling procedure is explained in the second script.
