 * Revision 1.3  2000/11/09 18:41:31  rokrau
 * The first commit to the sourceforge repostory. Update of all
 * intermediate changes makes this the official repository from now on.
 *
 * Revision 1.3  2000/11/09 17:56:14  rokrau
 * "Virtual" constructor for a VectorI from rows and columns of MatrixFI.
 *
 * Revision 1.2  2000/10/27 17:08:09  rokrau
 * some fixes for integer matrices
 *
 * Revision 1.1  2000/10/24 06:03:04  rokrau
 * Split header files, made Ref constructor private w/ some drastic consequences for
 * Ref operators. A lot of minor changes.
