 % Evaluates the likelihood of a nonlinear model with a particle filter allowing eventually resampling.
-%
-% INPUTS
-%    ReducedForm     [structure] Matlab's structure describing the reduced form model.
-%                                       ReducedForm.measurement.H   [double]   (pp x pp) variance matrix of measurement errors.
-%                                       ReducedForm.state.Q         [double]   (qq x qq) variance matrix of state errors.
-%                                       ReducedForm.state.dr        [structure] output of resol.m.
-%    Y                      [double]    pp*smpl matrix of (detrended) data, where pp is the maximum number of observed variables.
-%    start                  [integer]   scalar, likelihood evaluation starts at 'start'.
-%    mf                     [integer]   pp*1 vector of indices.
-%    number_of_particles    [integer]   scalar.

-% OUTPUTS
-%    LIK        [double]    scalar, likelihood
-%    lik        [double]    vector, density of observations in each period.

-% NOTES
-%   The vector "lik" is used to evaluate the jacobian of the likelihood.
