continued work on developing structured query functionality using the QuerySpecification class -- incomplete still

minor changes to TextNode

added incomplete classes for structured query

added result-set filter to DBSimpleQuery to only return specified document type

changed getDocID() only to:
return docid;

put checkURLConnection(systemId) before
its register in db or using from the parser

rewrote DBSimpleQuery and associated classes to no longer use Oracle's hierarchichal query syntax -- now this should work with any JDBC compliant backend DB

assign rootnodeid, docid for every node in xml_nodes table by given document

to use single transaction
