Metacat

Need feature in metacat that allows the client to specify if only a partial
resultset should be returned for a query. For example, the client should be
able to say "return records 1-100" and get only those records, then in another
pass say "return records 101-200", etc. The client may be required to submit
the query each time, or maybe there is a "Get next batch" action where a query
is cached in the session object and successive resultsets are returned to the
client as each batch is requested.
