Detailed Description
template<typename _Graph, typename _Traits = DefaultWriterTraits>
class lemon::EdgeMapWriter< _Graph, _Traits >
The lemon format can store maps in the edgeset. This class let you make distinict section to store maps. The main purpose of this class is a logical separation of some maps. The other useful application could be to store paths in edge maps.
