[SVN r24201]
Minor tweaks


[SVN r24202]
boost/graph/brandes_betweenness_centrality.hpp:
  - Add the ability to compute the edge betweenness centrality
  - Allow dummy_property_map to be used for the (vertex) centrality map
    (the edge centrality map also supports this).

boost/graph/named_function_params.hpp:
  - Add centrality_map named parameter
  - Add edge_centrality_map named parameter

boost/graph/properties.hpp:
  - Add vertex_centrality and edge_centrality properties

libs/graph/test/brandes_betweenness_centrality_test.cpp:
  - Test edge centrality

libs/graph/doc/brandes_betweenness_centrality.html:
  - Document the interface changes needed to allow computation of edge
    centrality, along with the new named parameters.

libs/graph/test/layout_test.cpp, libs/graph/test/Jamfile:
  - Test of the layout algorithms

libs/graph/doc/table_of_contents.html:
  - Add section on graph layout algorithms

libs/graph/doc/brandes_betweenness_centrality.html:
  - Trivial tweaks
