/**
 * @class INDIListener
 * INDIListener is responsible for creating ISD::GDInterface generic devices as new devices arrive from
 * ClientManager. It can support multiple ClientManagers and will first create a generic INDI device.
 * Upon arrival of INDI properties, INDIListener can create specialized devices (e.g. Telescope) if it
 * detects key Standard INDI property that signifies a particular device family. The generic device
 * functionality is extended via the Decorator design pattern.
 *
 * INDIListener also delegates INDI properties as they are received from ClientManager to the appropriate
 * device to be processed.
