Updated find_max_factor_graph_nmplp() to use the version of the algorithm from
...
the 2011 paper Introduction to dual decomposition for inference by David
Sontag, Amir Globerson, and Tommi Jaakkola since the original 2008 paper had an
error in the algorithm that negatively effected its convergence. Thanks to
James Gunning for pointing this out.

changed the interfaces to these functions slightly. Instead of taking a double that
determines how we decide if boxes match, they now take a test_box_overlap object.
