// single line Singletons
/*
DA RULES OF DA SINGLETON, MAHN

There are essentially three things to remember about the Singleton:

A singleton has to be unique. This is why it's called a singleton. There can only be one instance for the lifetime of the application it exists in. Singletons exist to give us singular global state. Such examples are NSNotificationCenter, UIApplication, and NSUserDefaults.
To maintain a singleton's unique-ness, the initializer of a singleton needs to be private. This helps to prevent other objects from creating instances of your singeton class themselves. Thank you to all who pointed that out to me :)
Because of rule #1, in order to have only one instance throughout the lifetime of the application, that means it needs to be thread-safe. Concurrency really sucks when you think about it, but simply put, if a singleton is built incorrectly in code, you can have two threads try to initialize a singleton at the same time which can potentially give you two separate instances of a singlet
