Hello all

Here is another sample program that demonstrates the use of bindings for
Popup Button.
The information information that is bound to in the NSArrayController is a
customer class called Person.cs that implements the KVO model.


To get this sample to work a change to NSMutableDictionary.cs is necessary
as follows:

		// Commented out as this was not working.  Kenneth J. Pouncey 2010/11/18
//		public bool ContainsKey (NSObject key)
//		{
//			if (key == null)
//				throw new ArgumentNullException ("key");
//			var keys   = NSArray.FromNSObjects (new [] {key});
//			var values = ObjectsForKeys (keys, marker);
//			return object.ReferenceEquals (marker, values [0]);
//		}

Once that is commented out it will use the base class's ContainsKey method
which does a simple check that works.
