Abstract:  View controller for the service instance list.

 This object manages a NSNetServiceBrowser configured to look for Bonjour

services.

 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, the

corresponding NSNetService is added to the array.

 When a service goes away, the corresponding NSNetService is removed from the

array.

 Selecting an item in the table view asynchronously resolves the corresponding

net service.

 When that resolution completes, the delegate is called with the corresponding

NSNetService.
