%
% mktemplate(problemname)
%
%   problemname = name of new user directory and problem functions
%
% This function will create a directory, 'problemname' and place in it 5 m-files:
%
%       problemname_init
%       problemname_new
%       problemname_cost
%       problemname_perturb
%       try_me
%
% which comply with the satools method signatures.  The four files
%       problemname_*
% are functional, but only in the sense that X and W are null and
% the cost function returns a random number.  The mktemplate function
% is a convenience tool from which the user can fill in their particular
% problem definition.
%
% After execution, the new directory will be the users current directory.
