00032 // Description: This file contains the class definition for ElementIter.
00033 // ElementIter is an abstract base class. An ElementIter is an iter for 
00034 // returning the elements of an object of class  Domain. ElementIters 
00035 // must be written for each subclass of Domain (this is done for 
00036 // efficiency reasons), hence the abstract base class.
