compiles and passes tests, but some potentially code-breaking changes in:
Marginals.h - order of arguments had to change since `factorization` has a default value
EliminatableFactorGraph.h - marginalMultifrontalBayesNet and marginalMultifrontalBayesTree no longer accept `boost::none` as a placeholder to specify later arguments
Notes:
EliminateableFactorGraph.h - `orderingType` is no longer needed in function overloads that specify ordering, but I left it for the time being to avoid potential code breaking
