+- Idea: a FactorGraph and a RegionGraph are often equipped with
+extra properties for nodes and edges. The code to initialize those
+is often quite similar; maybe this can be abstracted to classes
+like ExtFactorGraph and ExtRegionGraph (Ext stands for Extended), e.g.
+template <typename NodeProperties, typename EdgeProperties>
+class ExtFactorGraph : public FactorGraph {
+       public:
+               std::vector<NodeProperties>               nodeProps;
+               std::vector<std::vector<EdgeProperties> > edgeProps;
+       // blabla
+}
+A disadvantage of this approach may be worse cachability.
+- http://www.boost.org/development/requirements.html#Design_and_Programming
+- Would it be a good idea to cache second-order neighborhoods (delta's) in BipGraph?
+- Would it be a good idea to add the variable label -> index hashmap in FactorGraph,
+  to replace the linear searches that are performed every time for findVar()?
+  No, a better idea is to avoid calls to findVar() as much as possible.
+- Can the FactorGraph constructors be optimized further?
+- Move FactorGraph::_normType somewhere else (maybe to InfAlg or DAIAlg<T>)
+- Remove updatedFactor
+- Add Exceptions framework; this can e.g. be used as follows: if *.logZ() is
+called, it can return an exception if this method is not implemented, and the
+caller can catch this exception and handle it correctly. Then, you don't need
+a hasLogZ function/constant that tells whether this functionality is available.
+- Add an option to tests/test that it doesn't report the time needed; this is
+useful for the regression testing.
+
+DONE IN PREVIOUS COMMITS:
+- Added a few methods to BipartiteGraph
+- Improved ClusterGraph implementation (taken from SVN head)
+- Improved MaxSpanningTree algorithm (using boost::graph library, taken from SVN head)
+- Updated doxygen.conf
+- Made compatible with Visual C++
+- Merged improved index.h from svn
+- Rename stateSpace -> states
+- Optimized Diffs
+- Renamed Regenerate() -> create() 
+
+TODO FOR RELEASE:
+- Test Visual C++ compatibility
+- Figure out which libraries are required and document in README
+  boost headers, boost::program_options library
+
