need query execution module
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.

Finished. The Query class encapsulates the constraints that should be used for
searching, and contains an "execute()" method that will launch either a local
query, a metacat query, or both, and returns a single, integrated ResultSet.
This ResultSet has a reference to the Query embedded within it, so it can be
accessed again later for revision or re-execution.
