Neighborhood Ratings and Collection Spawn

Each neighborhood in the city will have a development rating: a score given to a neighborhood that is based on a combination of the number of developed properties and their quality (elements that affect the quality of development include size, residents associated, supplemental items, number of businesses, and so on). Once a neighborhood has reached a certain development rating, it will automatically spawn a collection for that neighborhood (if one does not yet exist) and further advancement in the development rating will lead to an increase in the collection boost.
