Re-assigning to original developer for easier retrieval later on.

Merged to master branch.
To-do:

• Add documentation to Google doc referenced in the project README.md explaining how a developer can create and deploy their own client secret and key for social authentication.

Some notes:

• There is no problem with redirecting to localhost.
• To use settings.py keys, you must open http://localhost:8000
• For test and production sites, make new keys

I have removed generated migration files in Download and submit_app folders.

• Functional review completed with no error. Was able to set up and run database. Clicking on "login" triggered request to Google auth service, but halted due to expected OATH error:

"The redirect URI in the request, http://127.0.0.1:8000/accounts/complete/google-oauth2/, does not match the ones authorized for the OAuth client."

• I am not sure how a developer can register a redirect URL that references localhost. Srishti Tiwari found a workaround for the Cyverse integration project.

• Please submit a pull request.

Here I have used my personal Google account to create Oauth2 Client ID and Secret Keys. We need to change accordingly in settings.py if we want to use IGBs Google account
