Customizable tournament schedule

[SheaBelsky]

• Prompt the team for their team number, store this within the tournament's state, then send a request to Ezra to get all events and times, from event signups and specified on events themselves
• Write an API on Ezra that lists all events (times and locations) that a team is in based on their team number
• The user selects which events they want to receive notifications for, and Firebase subscribes them to topics based on the tournament and event (create some unique key to identified a tournament and event, ${tournamentKey}_${eventKey}?
• On Ezra itself, push notifications should be sent prior to these events beginning. These push notifications should be scheduled on the day before the tournament, and sent 15 minutes prior to the event occurring. The notification should include the event time, and location if specified.
• When returning to the Schedule page, it should show a list of events that the team is attending. This list should be stored locally in the tournament state.
