* :class:`.Column` objects now have a ``metadata`` attribute which may be used
in the column description (if the ``--description_file`` option is used).
Processing functions can set the metadata for newly added columns.
* New ``metaproc`` plugin type to manipulate column metadata.
* All processing functions accept a ``metaproc`` argument, allowing a
``metaproc`` function to be applied to any column metadata that is returned
by the processing function..
* The :func:`.binariseCategorical` function sets the categorical value as
column metadata on the new binarised columns.
