 * Download: https://github.com/JonoPorter/Roku-Tv
 * Description:
 * This is a child device.  To use this device you simply need to install the device type handler.
 * The parent device will take care of add instances of the device handler for each application that
 * needs to be activated.  As this device is a generic push-button with a momentary switch, simillar to
 * the scene controllers,  in a future version this will be modified to be a generic momentary switch child
 * device instead.
