[Ifeffit] modeling significant defects and molecules

[Bruce Ravel]

Carl,

See

https://speakerdeck.com/bruceravel/modeling-non-crystalline-samples

particularly the bit on slides 11 and 12.

The bottom line is that Atoms is *a* starting point, not *the*
starting point.  It is just one way of making input data for Feff, not
the only way.
