Tagging UpdateRequestProcessor

It would be cool to have a Solr URP that does text tagging and applies the results as fields. The referenced documents from tagging might include metadata that can be copied to the current document going through the URP. It might very well be demonstration in nature, as applications are likely to have specific needs here. Nonetheless it's great to start with something instead of from scratch.
