[Ifeffit] viewing individual Fourier components with Athena

Basically, I have been asked to plot what Artemis gives for the theory 
when an individual path is plotted, except I'm supposed to do it for the 
raw data...that is, plot the individual paths that sum to the observed 

However, looking at the picture from some old rhodium dimer EXAFS given 
to me by the good guy that signs my checks ;-) (a pic I'm supposed to 
use as a guide), I'm "chasing a rabbit."  Problem solved (it's a "use 
the theory, Homer" moment, i.e. DO'OH!).

Thanks for the help!
