Specs:
- Have a CLI for interfacing with the application - typing './lib/boston_events' launches CLI.rb which allows users to explore events currently going on in the Boston area.
- Pull data from an external source - the event categories and events are scraped from the ArtsBoston calendar, http://calendar.artsboston.org/
- Implement both list and detail views - the CLI first presents a list of categories the user chooses from. Typing in a category number loads a list of current events in that category. The user can then select an individual event to see details.
