// Parent class for all addressable LED strips.
// Partially based on work by and (c) 2011 Jelmer Tiete
// whose library is ported from the Arduino implementation of Adafruit Industries
// found at: http://github.com/adafruit/LPD8806
// and their strips: http://www.adafruit.com/products/306
// Released under the MIT License: http://mbed.org/license/mit

// This is a pure virtual parent class for all LED strips, so that different types
// of strip may be used in a single array or container.
