Today and tomorrow we'll build a very simple restaurant review app.

This app will:
- show a list of restaurants it knows about
- show an individual page for a restaurant with reviews
- allow adding reviews
- allow creating new restaurants

# Bicycles, docking stations, vans, central system to control the vans, people

# people would ride bikes
# vans would move them around
# a central station would control the vans
# repair facility would take the broken bikes and fix them
# repaired bikes would be delivered to stations
# report on the most/least used stations
# bikes would be taken out of service after 1000 rides
