+% SET_PARAMS Set the parameters (fields) for a belprop_inf_engine object
+% engine = set_params(engine, name/value pairs)

+% The following optional arguments can be specified in the form of name/value pairs:
+% e.g., engine = set_params(engine, 'tol', 1e-2, 'max_iter', 10)
+%
+% max_iter - max. num. loopy iterations 
+% momentum - weight assigned to old message in convex combination 
+% tol - tolerance used to assess convergence 
+% maximize - 1 means use max-product, 0 means use sum-product
