%'check_files': check the path, modification date and svn version for all the
%  function in the toolbox UVMAT. Called at the opening of uvmat. Adds the
%  uvmat path to the Matlab path if needed.
%----------------------------------------------------------------------
% function [errormsg,date_str,ver]=check_files
%
% OUTPUT:
% errormsg: error message listing functions whose paths are not in the directory of uvmat.m
% date_str: date of the most recent modification of a file in the toolbox
% ver : svn version in case this is a  svn repository
