[Ifeffit] Can Artemis Simulate a FT Spectrum?

[Matt Newville]

Hi Robert,

Starting from Artemis' Theory menu, you can build a set of Feff Paths
that correspond to your model (say, starting with crystallographic
data).  As you do this, you can import these paths into  the current
project.    Once imported, use the Sum menu to add up paths to make
chi(k).
