 * This is a marker interface, which a class can implement to
 * act has a client data carrier. 
 * 
 * This class stores any data associated a client during its 
 * session with the QuickServer. This class can be used by 
 * {@link ClientCommandHandler} class to store any data about 
 * the client it may need in the next call to 
 * {@link ClientCommandHandler#handleCommand} from the same client.

 * that pool, instead of creating an new instance for every client.
