/**
 * DesignContextListener is the event listener interface for DesignContexts.  These methods are called
 * when a DesignBean is created, deleted, changed, or moved.  This includes the DesignBeanListener
 * methods as well, so effectively a DesignContextListener is a listener to *all* DesignBeans in a
 * context.
 *
 * GLOBAL CONTEXT LISTENERS:  If you wish to provide a global IDE-wide
 * DesignContextListener, you can declare the following static method in your DesignInfo class.
 * When the DesignInfo for your bean is loaded, this static method will be looked for via
 * reflection and called if it exists:
 *
 * 
 *    public static DesignContextListener getGlobalDesignContextListener() { ... }
 * 
 *
 * If this methods is declared in a DesignInfo implementation class, it will be called when the
 * DesignInfo is loaded, and added to a static list of global listeners. This listener will be
 * notified of *every* event that happens in the IDE, so please use sparingly!
 *
 * IMPLEMENTED BY THE COMPONENT AUTHOR - This interface is designed to be implemented by
 * the component (bean) author.
