/**
 * A <code>Server element represents the entire Catalina
 * servlet container.  Its attributes represent the characteristics of
 * the servlet container as a whole.  A <code>Server may contain
 * one or more <code>Services, and the top level set of naming
 * resources.
 * <p>
 * Normally, an implementation of this interface will also implement
 * <code>Lifecycle, such that when the start() and
 * <code>stop() methods are called, all of the defined
 * <code>Services are also started or stopped.
 * <p>
 * In between, the implementation must open a server socket on the port number
 * specified by the <code>port property.  When a connection is accepted,
 * the first line is read and compared with the specified shutdown command.
 * If the command matches, shutdown of the server is initiated.
 * <p>
 * <strong>NOTE - The concrete implementation of this class should
 * register the (singleton) instance with the <code>ServerFactory
 * class in its constructor(s).
