I added both of your examples into the Boost trunk in r64063 (with a small 
change in r64064).  Please check and see if you are fine with them.  I put 
implicit_graph.cpp in as-is (except for changing a quote to a normal ASCII 
quote); I tweaked astar_maze.cpp a bit (changing the distance type to 
double and adding missing braces around an initializer) to fix compiler 
warnings.  Thank you for your contributions to BGL.
