Jeff Pittman	e56cf56279	Added a base class called CollectionAdapter, with subclasses ListAdapter and DictAdapter. Added the start of trim, cut, and scroll_to methods in these adapters. Tried various combinations of examples and tests for working with sorted_keys and data in DictAdapter, settling down on bindings firing selection updates and refreshes that are stabilizing. Added a list_ops.py example showing use of the new trim, cut, and scroll_to methods, and also ways to use AliasAdapter and binding to a property setter. Removed ObjectAdapter and ObserverView, in part because of working out the approaches shown in list_ops.py, and also because it is better to take a fresh try at these classes if desired in the future.	2012-08-17 12:20:08 -05:00
