function check_prior_bounds(xparam1,bounds,M_,estim_params_,options_,bayestopt_)
% function check_prior_bounds(xparam1,bounds,M_,estim_params_,options_)
% checks the parameter vector of violations of the prior bounds
% Inputs:
% -xparam1 [double] vector of parameters to be estimated (initial values)
% -bounds [vector] vector containing the lower and upper
% bounds
% -M_ [structure] characterizing the model.
% -estim_params_ [structure] characterizing parameters to be estimated
% -options_ [structure] characterizing the options
% -bayestopt_ [structure] characterizing priors
