Message:

Added some code for tk labels - options to take a single field and store its values as individual metadata fields with true value. eg wmtb.TKLabel=tk.Clan,tk.Attribution =>tk.Clan=true, tk.Attribution=true. Implemented for tk labels, but then not needed as this is handled by xslt instead. Leaving this here in case useful in the future
