Subject: [PATCH] Text-slicer: add support for document metadata fields
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The metadata for each field is in a tiddler tagged
`$:/tags/DocumentMetaData` with the field `caption` being the displayed
caption for the field and `field` being the name of the field.
`field-type` is the type of the field, and can be “string” or “list”.
