begin Installation docs

create Installation Instructions doc
list requirements (needs to be filled out)
about half of the quick-n-easy install docs are done (needs web server
section still)

detailed installation instructions incomplete at this point

major work on INSTALL.md

small wording changes in the quick install/extraction section
note that the config file needs to be copied from the sample

work on the more detailed instructions:
-extracting done with note on which files have paths
-mysql DB: note which files have creds hard coded

INSTALL.md: table of contents

add a test TOC to INSTALL.md

INSTALL.md: more TOC stuff

use doctoc to automatically do a TOC on this document.
