Alex Coyle / Mbed 2 deprecated PatternMatching

Uses a randomly generated pattern that is output in the forms of colors on the RGB LED. The user matches this pattern and, if correct, the pattern increases by one in length. If the user beats the high score they will be prompted to input their initials for the high score screen.
