New endpoint-based backend for chasing interface

[jthielen]

Related to #1, the web-based front-end also needs a python backend on the server. This will be database-state driven (everything is maintained in the database files), but I'd also like to use objects to keep things neat in the script. See https://github.com/isuams/chase_simulation/blob/master/endpoints/chase.py for current progress.

Also, some new features are being added along with way with this:

• Budget
• Point tallying
