Title: LM4F GPIO

All of a sudden, the world makes a lot more sense. It is not because people are coalescing together, it is not because politicians have started making sense.
No, it is because we can finally replace those cryptic register accesses in our LM4F code, that's why. The guy calls it "the GPIO API". Fancy name, eh?
