nt_verbose

previous=nt_verbose(new) - set/get global verbose flag

  previous: flag value currently stored

  new: new flag value to store [default: same as previous]

 Usage:
   if nt_verbose; display('feedback'); end % display feedback if flag on
 
   nt_verbose(1); % set flag to 1

   previous=nt_verbose(1); % set flag after storing previous value
   nt_verbose(previous); % restore previous value
