Ollies Arduino multitasking program

In few hours grandson Oliver learned:

* Functions
* Variable types
* Superloop multitasking - NO delay( ) !!!!
* Finite State Machines

This program simultaneously:

- Blinks 3 LEDs (including LED_INBUILT) at different, non-harmonically related rates;
- Cycles an RGB LED through 7 colour combination with a state machine
- Modulates the flash rate of an LED with sensing of light on an LDR

Oliver is 13. 95% of hobbyists can't do this.
