// Revision History: | |
// 03 May 2001 Jeremy Siek | |
// Generalized the property map iterator and moved that | |
// part to boost/property_map.hpp. Also modified to | |
// differentiate between const/mutable graphs and | |
// added a workaround to avoid partial specialization. | |
// 02 May 2001 Francois Faure | |
// Initial version. | |
