The OpenNI::DeviceDisconnectedListener class provides a means of registering for, and responding to
when a device is disconnected.
onDeviceDisconnected is called when a device is removed from the system. Note that once a device is removed, if it was opened by a Device object, that object can no longer be used to access the device, even if it was reconnected. Once a device was reconnected, Device::open() should be called again in order to use this device.
To use this class, you should write a new class that inherits from it, and override the onDeviceDisconnected method. Once you instantiate your class, use the OpenNI::addDeviceDisconnectedListener() function to add your listener object to OpenNI's list of listeners. Your handler function will then be called whenever the event occurs. A OpenNI::removeDeviceDisconnectedListener() function is also provided, if you want to have your class stop listening to these events for any reason.
