DsgeLikelihood_hh.m was removed when DsgeLikelihood.m was replaced by dsge_likelihood.m
DsgeLikelihood_hh.m needs to be replaced by dsge_likelihood_hh.m that is needed by newrat.m and tests/fs2000/fs2000d.mod
All the Kalman filter routines needs also to return llik, the vector of loglikelihood per observation.
