LPC1114 delay functions writing notes

I forgot that the mpu in the evaluation board has no operating system in it.  So there is no delay function available as in Arduino or Raspberry Pi.  So I wrote my own, using brute force stop watch timing experiments.

The delaySecond() and delayTenthSecond() are coarse but OK for my basic testing.
