Obtain all bike parking locations

* Set a route '/spots' to obtain all parking spots
* Spots obtained from https://data.sfgov.org/resource/w969-5mn4.json
* Installed requests to make url requests simpler,
  which is at http://docs.python-requests.org/en/latest/

Next steps:
* Unfinished parking locations are included in this list, so it will
  need to be pared down to filter out those locations that are not
  currently usable
Add installed resources to the README.md
