Adding apartment to our api project

rails-apartment-notes.md

1. add apartment to gemfile
2. run initializer to generate config/apartment.rb
3. Create our Event model (which maps to schemas)
4. before_validate: create self.schema that uses .parameterize.underscore from self.name on event model
5. after_create: create new apartment tenant on the event model
6. Set up the config to ignore a few of our models that are public
7. hard code the config to select a single event schema, for now
8. migrate over all the data:

scans = Scan.all
Apartment::Tenant.switch!('old-event')
scans.each{ |s| Scan.create(s.attributes) }

that was it.
