function putmesh(mesh, filename, format, varargin)
% PUTMESH saves the current mesh to a file with designated file name and
% format. 
% 
% USAGE
%    putmesh(mesh, filename, format, varargin)
%
% INPUT 
%       mesh:  current mesh structure
%   filename:  file name you want to use to save mesh and solution
%     format:  picture format 
%              supported format includes ps, eps, ps2, eps2, jpeg, png,
%              etc (see the help of MATLAB command print), default format
%              is "epsc".
