Changeset 15836 for gsdl/trunk/src

Timestamp:

Message:

(Adding dynamic classifiers) Not sure if this is necessarily the best place to do this, but added the ability to request the documents from a "get_documents_with_metadata_value()" call to be sorted based on a certain metadata element. Thanks to John Thompson for the SQL statement help.
