function [newbel, loglik] = dbn_init_bel(engine, evidence)
% DBN_INIT_BEL Compute the initial belief state (hmm)
% [newbel, loglik] = dbn_init_bel(engine, evidence)
% evidence{i} contains the evidence on node i in slice 1

obslik = mk_obs_lik(engine, evidence, 1);
[newbel, lik] = normalise(engine.prior(:) .* obslik);
loglik = log(lik);
