/* The only subclassResponsibilities in IndexedCollection are:

      insertElement:atIndex:
      removeElementAtIndex:
      elementAtIndex:

   but subclass will want to override others as well in order to 
   increase efficiency.  The following are especially important if
   the subclass's implementation of "elementAtIndex:" is not efficient:

      replaceElementAtIndex:with:
      swapAtIndeces::
      shallowCopyReplaceFrom:to:with:
      sortAddElement:byCalling:
      removeElement:
      firstElement
      lastElement
      shallowCopyFrom:to:
      withElementsCall:whileTrue:
      withElementsInReverseCall:whileTrue:

   and perhaps:

      appendElement:
      prependElement:
      indexOfElement:
      withElementsInReverseCall:
