Library to allow the use of Arduino specific language with the mbed

Dependents:   Gameduino Factory_monitor_0v1 mbed_mindflex NEW_NFC_TEST

This is a library for allowing the use of programs written for the Arduino with the mbed. This was started for use with the Gameduino shield Library. It is currently uncomplete and not fully tested, but I don't see myself spending time on it. See TODOs and check http://arduino.cc/en/Reference/HomePage for missing parts
