FoodTruckIntent: Ask for food truck by neighborhood

[jmartini]

Is your feature request related to a problem? Please describe.
Often users ask for food trucks in a neighborhood as opposed to a particular address (ex: food trucks in Jamaica Plain). This is how the City of Boston lists food trucks as well.

Describe the solution you'd like

User	Alexa, ask Boston Info if there are any food trucks in the Financial District?

I would like to work on this issue, if no one else is already working on it.
