 * File     : ledRGB.h
 * Abstract : Header for LedRGB class managing an RGB strip.
 *            The user will be able to interact with the 
 *            configured strip and get its status.
 *
 * strip    : 
 *            Parameter 1 = number of pixels in strip
 *            Parameter 2 = pin number (most are valid)
 *            Parameter 3 = pixel type flags, add together as needed:
 *            NEO_KHZ800  800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
 *            NEO_KHZ400  400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
 *            NEO_GRB     Pixels are wired for GRB bitstream (most NeoPixel products)
 *            NEO_RGB     Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
