Story:
    Auto build index every a few seconds
  Description:
    Currently forum administrator should run indexbuilder manually 
    to add newly posted threads to index


Extension:
    User can create task later, to do that, following the steps below:
      1.create a task:
        extends the TimerTask class, and implement it's run() method
      2.add it to TaskRunner in ForumActionServlet
        taskRunner.addTask( theTask, interval );


CRC Card:

IndexBuilder
---------------------------------
indexDir
buildIndex()

BuildIndexTask extends TimerTask
---------------------------------
run()

TaskRunner
---------------------------------
addTask( TimerTask task )
addTask( TimerTask task, int interval )
toString()


working item:
    refactoring IndexBuilder
    write BuildIndexTask
    write TaskRunner
    modify ForumActionServlet
    test
