 * REVISIONS and CHANGES 
 *  - 10/05/2002   V1.0   Thomas Forbriger
 *  - 16/12/2002   V1.1   (thof)
 *                        - compiles and works
 *  - 28/12/2002   V1.2   (thof)
 *                        - new term for containers of const elements
 *  - 31/12/2002   V1.3   (thof)
 *                        - initializing an aff::ConstSharedHeap to a defined
 *                          size is a useless exercise
