*	Refactor the formatter to an interface and rename it	Grant Ammons	2017-10-03	1	-0/+5
	This change refactors the formatter to be an interface called Printer. `NewApp` will use the functionality of `ScreenPrinter`, which is what I refactored the old `Formatter` class into. There is a new class the implements the `Printer` interface called `MemoryPrinter`, which will simply store the `groups` as they were passed to it. This will allow tests in `app_test.go` to become much more powerful, since `App` no longer needs to be tightly coupled to printing to the screen.
