 * A console page participant is notified of page lifecycle events such as
 * creation, activation, deactivation and disposal. A page participant can
 * also provide adapters for a page. Participants are contributed via the
 * <code>org.eclispe.ui.console.consolePageParticipants</code> extension point.
 * <p>
 * Participant behavior is implementation dependent. For example, a page participant
 * could add actions to a console's toolbar by accessing a its page's action bars.  
 * </p>
 * <p>
 * Following is an example extension definition.
 * <pre>
 * <extension point="org.eclipse.ui.console.consolePageParticipants">
 *   <consolePageParticipant
 *      id="com.example.ExamplePageParticipant"
 *      class="com.example.ExamplePageParticipant">
 *   </consolePageParticipant>
 * </extension>
 * </pre>
 * </p>
 * The example page participant is contributed to all console pages. An optional
 * <code>enablement</code> attribute may be specified to control which consoles
 * a page participant is applicable to.
 * <p>
 * Clients contributing console page participant extensions are intended to 
 * implement this interface.
