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