* Introspection-based automatic type conversion from a generic C++ object

to a specific Python object.  The conversion takes place in the following
places.
- Interface0DIterator_getObject (BPy_Interface0DIterator.cpp)
- Director_BPy_BinaryPredicate1D___call__ (Director.cpp)
- Director_BPy_UnaryPredicate1D___call__ (Director.cpp)
- SVertex_viewvertex (BPy_SVertex.cpp)
- BPy_FEdge_from_FEdge (BPy_Convert.cpp)
This is a tentative list and more conversions are expected to be added.

* Added the following two converter functions to BPy_Convert.{cpp,h}:
- BPy_NonTVertex_from_NonTVertex_ptr
- BPy_TVertex_from_TVertex_ptr
