Documentation to support new User changes, including ghpages

I have written some docs for the changes, plus a instruction
on pushing the docs to gh-pages on github
Add README
Add tests into mix
Add in usermodels etc

I am supply a views.py - deals with routes and HTTP, then it calls UserMOder
 whcih does the main job of work and talks through backend to SQL dbase.
cnxbase.py is used to probvide basic jsonification through inheritence.
prepopulate now part of testing functions
Add in license conditions to py files

License is put at top of each file, via automated script in bamboo.
Changes to wording can be made and agreed as needed.
Add copyright stanza to doc files
Remove emacs crud
Merge pull request #15 from Connexions/new_user_dbase_search

New user dbase search - this is a little old - should have been pulled across earlier.
