delayMicrosecondsHard re-written - again. Added a serialRead example program, and added in the okLed to the examples too. Updated/checked some of the GPIO/PWM code. Added in some experimental servo and tone generating code and and example or 2. Tweaks to the gpio command to correctly load the I2C modules too.
