[Ifeffit] getting chi(r) information out of command line IFEFFIT

[Matt Newville]

Sean,

Like Bruce (I think), I'm having trouble understanding what
    "get the chi(r) information for the fit"
means.   Do you mean something like the output of
    show @paths
    show @variables
or maybe you want plot() or write_data()?  I can't tell.

In any case, it's probably better to figure out how to get what sort
of output you're looking for with a much simpler problem before
tackling one that has many data sets.
