Title: Add a bounding box for the responses

Add a bounding box for the responses to the survey object returned by `GET /api/surveys/SURVEYID`.

Use the Mongo aggregation framework to calculate the bounding box. This was faster than other methods tested, but we can also change the algorithm behind the scenes without affecting the API.
