#169 fixed Fixes and improvements for lemon/bits Peter Kovacs Peter Kovacs
Description

[75cf49ce5390] adds missing tags to graph implementations and indicators in traits.h. They are needed because the tags for arcs and edges are now separated in core.h.

[f58410582b9b] contains doc improvements for tools in lemon/bits. I know that these docs are not public now, but it may help the developers. If you like it, then push it to the main repo.

#170 fixed Critical bug fix in SmartDigraph::split() Peter Kovacs Peter Kovacs
Description

The following code causes "Segmentation fault" error in the 1.0 release as well as in [9194a12c52e6].

  typedef lemon::SmartDigraph Digraph;
  DIGRAPH_TYPEDEFS(Digraph);

  Digraph G;
  Node n1 = G.addNode(), n2 = G.addNode(), n3 = G.addNode();
  Arc a1 = G.addArc(n1, n2), a2 = G.addArc(n2, n1),
      a3 = G.addArc(n2, n3), a4 = G.addArc(n2, n3);

  Node n4 = G.split(n2);

The attached patch [99dcd99637ba] fixes this critical bug on the top of [9194a12c52e6]. However I think it would also worth to merge into the 1.0 release branch.
