X-ray scattering datafiles (This process MUST be automated in the future! ;) )

Obtained from NIST: http://physics.nist.gov/cgi-bin/ffast/ffast.pl

1) Use the tool get_xray_db_data - requires bash and wget, e.g.:

./get_xray_db_data Mo Mo.txt

2) Edit Mo.txt using an editor and strip out any html tags

3) "Massage" the header to make it similar to
