- BFD/DFS/Dijkstra compile test is done with skeleton::GraphSkeleton graph
and skeleton::ReadMap.
- 'skeleton::' is explicitely written instead of 'using namespace ...'
in graph_test.cc
- Output messages of type "makeRep(3)..." in unionfind_test.cc have been
changed in order not to confuse compiler output parsers.
