[Ifeffit] Ifeffit 1.0075

[Matt Newville]

Hi Everyone,

Ifeffit 1.0075 is now available.  There are some bug fixes
related to erasing paths, which caused serious problems with
artemis.  There was also a change in the guts of how the Perl
wrapper was built, as the older one failed to compile with gcc3.2
on RedHat 8.0.  I have not tried this on Mac OS X, and don't
foresee any problems, but if someone is brave enough to try it,
please let me know if it fails.

The most significant change in 1.0075 is the inclusion of Feff6
in the source tree and a Windows executable of Feff6 in the
Windows installer.  That right, there is now a free version of
Feff6 included with Ifeffit!!

The plan is to turn this version of Feff into a library that can
be called directly from the perl and python scripts.  That is,
the 'run feff' button on TkAtoms might actually work someday!! If
you're as thrilled about this as I am, don't hesitate to thank
John Rehr repeatedly.

There are new versions of sixpack, artemis, and athena in the
Windows installer.  The latest source code for these should be
downloaded from Sam's and Bruce's web pages.

Special Thanks to John, Sam, and of course Bruce,

--Matt
