In part two of this tutorial we apply a sorted transformation to our issues list. We
    construct a JTable to display the list with a column for each 
    important attribute of the Issue class. Finally we add support 
    to sort our JTable by the clicking on its column headers.
The SortedList is simply a wrapper that shows another 
      EventList in sorted order. Like all 
      TransformedLists, the SortedList listens
      for changes to its source list and adjusts itself when changes are made. By layering
      TransformedLists like SortedList and 
      AbstractFilterList, we are able to create flexible and powerful
      programs easily.
