427	Create build() routine for StaticDigraph that allows # of arcs to be set explicitly	Hoyt Koepke	Alpar Juttner	"Hello,

I recently tried used StaticDigraph with an iterator that used a forward-only traversal concept, as it was a thin wrapper to some rather complicated underlying structures.  The problem is that the std::distance() call cause the iterator to run through the entire set to get the number of arcs, even though this was something I knew beforehand.  Rather than create some sort of clumsy workaround, I found it easy to add another version of build() that permitted one to pass in the number of arcs explicitly.  It's possible that mine is a rare case, but in case people are interested, here is a patch that does this.  It's complete with appropriate documentation changes."	enhancement	new	major	LEMON 1.4 release	core	hg main
