Comment (by lkilcher):

 In case it wasn't obvious, the goal here is improving performance (reading
 small variables from files with large variables is slow when you have to
 read all of them).

 I tried adding a 'variable_names' kwarg to {{{mio.loadmat}}} to pass to
 {{{mat_reader_factory.get_variables}}} (see attached mio.py file), but I
 think this only changed which variables were passed to the output of
 loadmat rather than actually limiting which variables were read from the
 file.  Any ideas?
