Removed non standard functions togglePin, toggleLED,isButtonPressed, and waitForButtonPress. And updated all examples that used these, to use other functions. Note togglePin was used internally in shiftOut. Also note, that some of these functions were replaced by the code that was inside the non standard function e.g inside togglePin. In the longer term these internal maple function calls need to be replaced by high level Arduino API calls like digitalRead and digitalWrite where applicable
