[graph-tool] inferred weights distribution

Hello. After reading your "Nonparametric weighted stochastic block models" paper and trying weighted NSBM model. I'm trying to find inferred distribution (mixed) for weights (edge-covariates). How can I get them from the BlockState object? I need it to repeat your graphical analysis on different weight transforms from the paper. I guess somehow I can restore the "the marginal covariate distribution between groups r and s" from resulted object. Thank you, Valeriy
