/**
 * Base interface that defines the methods to initialize jWebSocket engine, servers
 * and plugins. The implementation of this class can initialize in different way. 
 * 
 * {@code JWebSocketXmlConfigInitializer} performs the initialization using
 * 'jWebSocket.xml' configuration file. 
 * 
 * {@code JWebSocketInitializer} performs the initialization directly using the source
 * classes and packages. This class enables user to write initialization code at compile 
 * time thus helping debugging their engine, servers and plugin logic.
