Edit from "Flux" to "Flux Operating Environment" in foe-for-research-admins
Added the Org-Mode versions of the Flux content from caen/hpc.

These were created by doing:
   curl -o page.html www.engin.umich.edu/caen/hpc/page.html
   pandoc -o page.org page.html
   emacs page.org [clean-up, add some org info, etc.]

They should be the "as-builts" for the caen/hpc website prior to the
addition of the Flux Operating Environment pages.
Added CSS hints; deleted Nyx, ICSE, CAC, and PhD program; added FOE
Instructions on using these files, and some export configs
