/*File: BrowserViewController.hAbstract:  View controller for the service instance list. This object manages a NSNetServiceBrowser configured to look for Bonjourservices. It has an array of NSNetService objects that are displayed in a table view. When the service browser reports that it has discovered a service, thecorresponding NSNetService is added to the array. When a service goes away, the corresponding NSNetService is removed from thearray. Selecting an item in the table view asynchronously resolves the correspondingnet service. When that resolution completes, the delegate is called with the correspondingNSNetService.
