DGNewTournamentViewController is almost fully functional now.
To do:
- Implement the rest of “Create” button.
	- Create the tournament
	- Segue to a view that lets the user select players.
- Create player selection view.
I was thinking about the data model and it made no sense for a “Player in tournament” to be a subclass of Player. It should be a many-to-many relationship with tournaments and with that in mind I modified the data model to reflect the proper relationships instead.
Creating a tournament implementation is now complete.
When the user selects a tournament from the initial view, the app transitions to a list of the players in the tournament.
Next steps:
1. Sort functions for players based on tie-breakers
2. Implement the view for the current round displaying the matches
