Add login interface to save marker information

[qtrandev]

Created items to discuss changes needed for this implementation:

1. Add log in and log out - email login at the simplest, Google or Twitter support additional
2. Add support for saving information in markers - may be Firebase
3. Possibly add custom markers

Log in / log out

TO-DO: Find out how to implementation this. Start with email/password?

Saving information

TO-DO: Look for ways to save information. If use MySQL, Postgres, or some other DB, then we need a separate running server since our code is client-side. If using Firebase, it might be simpler.

Userbase support

We don't expect many people using this in the beginning so expect maybe 100 test users at most. In the future, need to scale up.

I'm able to make a login/logout interface using Firebase and Polymer (https://www.polymer-project.org). Integrating Polymer into this ftlviz app might be a challenge. We also need to decide what to save in the markers once we log in - whether custom data for each marker or custom markers.

I might have an old php solution for creating user accounts and logging in and out but it requires access to a database to store user log in info. If you're planning on storing marker data then having a database can help for that as well.
