Sketch out a "query state" structure.

As yet it's completely unused, but the intention is that accumulated
state will be collected into one of these structures for each query, and
then passed around, to help reduce the need for silly arglists.  It's
possible that this structure will also grow a pointer to the adb itself,
and be the thing passed to the LSH callback; we'll see how that
develops.

// audioDBws.h -- web services interface to audioDB
//
//FIXME: this hard-coding of the service location might be right for
//its internal use at Goldsmiths (for now) but really isn't in
//general.  Find a way to bind this later (at install time?  Or maybe
//just require that the installer edit the resulting wsdl file?)
//
//gsoap adb service location: http://gibbons.doc.gold.ac.uk:20703/
