Moving dots in time.

/*

The goal of this test sketch is to run multiple strips where each dot could be turned on one after the other but with different times on/off between each pixel on each strip.

By: Andrew Tuline
Date: August, 2015

Assumptions:

- Each element in the array is greater than the one previous.
- The last element in the array is the end of the line.

Note that there are NO nasty 'for' or blocking delays.
