/**
 * @brief The MessageProcessor class implements a set of overloaded process() methods, with each handling a specific message type.
 *
 * When a CEC frame is received, the MessageDecoder converts the raw bytes into a message object and invoke the
 * corresponding process() function.
 * @n @n
 * Application that desires to process certain CEC messages should extend MessageProcessor class and provide customized
 * implementation of the overloaded process() method. The default processing in the base class is simply discarding the message
 * (and by doing so, serves as a message filter for the application).
 * @n @n
 * Here is an example code that sends an ActiveSource message by a Tuner device,
 * @code
 * CECFrame frame = (MessageEncoder().encode(
 *     Header(LogicalAddress(TUNER_1), LogicalAddress(TV)),
 *        ActiveSource(PhysicalAddress(phy0, phy1, phy2, phy3)));
 * Connection(LogicalAddress(TUNER_1)).send(frame);
 * @endcode
