spike for non municipality organization

@twneale, should something like this work? 

(don't merge, I haven't tested)
We might need a way to define Classification here - sorta like how Pupa raw does:

```python
class Holyoke(Jurisdiction):
    division_id = 'ocd-division/country:us/state:ma/place:holyoke'
    classification = 'government'
```

(So you can do `classification = 'sewer'` or something)
