Captain Morgan's Notifications -- Advanced Lab

Instructions

1. Check out what we have for you!

2. You'll find that in order to add a new pirate or a new ship, our AddPirateViewController and AddShipViewController have to grab FISPiratesDataStore and call its methods. This makes the controllers highly dependent on each other... let's reduce this dependency.

3. Make FISPiratesDataStore register to listen for NSNotifications.

4. Make each of your "add" controllers broadcast an NSNotification with the information that they take from the user attached as an NSDictionary.

5. Create categories on your Ship and Pirate classes, each with a convenience class method as shown below:

+(instancetype)shipFromDictionary:(NSDictionary *)dictionary
andContext:(NSManagedObjectContext *)context;

+(instancetype)pirateFromDictionary:(NSDictionary *)dictionary
andContext:(NSManagedObjectContext *)context;
```

Hint

Your NSNotificationCenter addObserver method should be placed inside of the init method of your FISPiratesDataStore. Don't forget to appropriately remove the observer as well!
