/* Declare the NeoPixel strip object:
*     * Argument 1 = Number of LEDs in the LED strip
*     * Argument 2 = Arduino pin number
*     * Argument 3 = LED strip color order

* The FastLED_NeoPixel version uses template arguments instead of function
* arguments. Note the use of '<>' brackets!
* 
* You can switch between libraries by commenting out one of these two objects.
* In this example they should behave identically.
