Between the time an instance is created and destroyed, a number of things can happen.
To simplify how things work, they are divided into three sections: startup, midlife,
and shutdown.

Each application object is a singleton object. Each instance gets it's own application
object which is an instance of the Application class.

These are all the standard event handler method of the application object
