Improve and redesign test programs + unify their output (ticket #25) - Move graph related utilities form test_tools.h to graph_test.h. - Move the contents of graph_utils_test.h to graph_utils_test.cc. - Rename map_test.h -> graph_maps_test.h. - Rename digraph_test.h -> graph_test.h. - Many improvements in the following files: * digraph_test.cc * graph_test.cc * graph_test.h * graph_maps_test.h * graph_utils_test.cc * bfs_test.cc * dfs_test.cc * counter_test.cc - Test programs print messages only if it really seems necessary. - Remove \file commands form .cc test files.
