function save_params_and_steady_state(filename)
% function save_params_and_steady_state(filename)
%
% For all parameters, endogenous and exogenous variables, stores
% their value in a text file.
% * for parameters, the value is taken from the last parameter
%   initialization
% * for exogenous, the value is taken from the last initval block
% * for endogenous, the value is taken from the last steady state
%   computation (or, if no steady state has been computed, from the
%   last initval block)
% Note that no variable type is stored in the file, so that the values
% can be reloaded (with load_params_and_steady_state) in a setup where
% the variable types are different.
%
% INPUTS
%   filename:   where to store the saved values
%
% OUTPUTS
%   none
%
% SPECIAL REQUIREMENTS
%   none
