Suggestion to break up the readme file into multiple files

[jkrick]

Then the main readme page that GitHub page renders can be a table of contents. It will then be a readme for the repo.

Instead of a single readme.md file that we have all the documentation in, it would be better to break this into smaller files. FAQ.md, data_access.md, login.md, quick_start.md, or whatever we would want to have in the table of contents.

Then in the rendering Brigitta will make it have a table of contents. and the readme will be a readme for the repo and not the content itself.
