[Ifeffit] k range

Hi Shelly, Steven, Scott,

Out of curiosity, how does kmax_suggest from chi_noise() or feffit()
agree with the somewhat elaborate determination of a good value for
kmax for noisy data that Shelly and Scott described?  The hope is
that kmax_suggest could give an idea for how far out the data is
worth analyzing, but it hasn't been run through the mill too much.

I don't know if artemis shows this value, so you might have to look
in the Ifeffit buffer, maybe even typing 
   show kmax_suggest
after doing a fit.

Thanks,

--Matt
