benchtimes -- Simple Interchange extension to add benchmarking of catalogs

Installation:

	1. Append interchange.cfg.add to your interchange.cfg file.
	2. Append catalog.cfg.add to the catalog.cfg for any catalog you
	   want to benchmark.
	3. Restart the server.
	4. Copy bin/benchtimes to a place where you can execute it. You
	   could possibly have to change the first line to point to a
	   proper perl, but almost any modern perl will do.
	5. Periodically run "benchtimes CATDIR/logs/bench.log" to
	   summarize high usage. Do "perldoc bin/benchtimes" for more
	   information.
