Sidebar: Searching for good material for presentation

Searching for good material combo for ANS14 presentation.
Decided that U and C are not that good.  Such high scatrat for C causes
partial negativities that make the best rendition with one mode...
Want to try SiC and UO2 like in TRISO particles.
Set up to see how 'good' material set is.  Use bash command in bascommand.sh.

Also commented out previous debug statement that was hanging around.
