AberLED shield library

Library for the bicolor LED (and TFT screen) shield used in CS12020

Template definition for teensy 3.0 style ARM pins using bit banding, providing direct access to the various GPIO registers. GCC does a poor job of optimizing around these accesses so they are not being used just yet. More...
