Need a query execution module that takes a pathquery document as input and
returns a resultset (in XML format) as output. The same module should be used
for both network and local queries. Initially, this means it will execute an
XPath Query locally, and a metacat query on the net, and merge the results into
one resultset (presumably by accession#), indicating where each result record is
located). Eventually this might turn into a metacat search locally if John's
attempts to port metacat to a local client work out. This is related to the
resultset handling widget that Matt is working on.
