Changed args_converter to take row_index as first argument. Fixed the list_two_up.py example, which needed explicit set to sorted_keys.

Added tests toward full coverage, revealing bugs in code that had never been reached. Simplified several parts of the API. Merged CollectionAdapter into ListAdapter, so now it goes: Adpater -> SimpleListAdapter, Adapter -> ListAdapter -> DictAdapter, with selection in ListAdapter, and DictAdapter.

Refactor for improved selection operations. SelectionSupport is no more as a separate mixin, and a new base adapter, CollectionAdapter, takes this code in, as well as the view caching code from AbstractView. Now CollectionAdapter is the hub for selection and view-handling operations. Made the default for selection to be restricted to views, with a new flag propagate_selection_to_data for this functionality. Started adding tests for adapters in isolation. Simplified initial selection and refreshing operations between adapter and listview.

Moved SelectableView out of adapters/mixins and into uix, and adjusted examples and tests. Added base Adapter tests, and a test to check views returned from adapters.

Changed ListAdapter to work with lists, removing complexity for having data as strings and a separate datastore. Removed DataStore and concept, and replaced with a new adapter, DictAdapter, that works straight with dicts. Updated examples and tests for changes.

Restored list_cascade_setter.py. Fixed comments about custom list adapter vs. using a setter-type binding.

Started moving to use of setter() in creating bindings between list adapters, with an example of a custom list adapter left in list_cascade.py.

Selection had no memory of previously selected items, because the data used in
...
the examples were just strings primarily. To further development with a more
realistic environment, a DataStore class was created, with simple set and get
property methods, operating on a key into a dict of records. The simple scheme
for the records is that they must all contain an is_selected boolean for
storing the state of selection. The fruit dataset was modified accordingly,
into two datastores: categories and fruits. A new simple dataset was also
created for integer data used in several examples.
For view instances to be associated with data records in a datastore, an index
property was added to SelectableItem. This index into the data list is used in
selection operations to keep selection of data items in sync with item view
instances.
When creating item view instances in ListView there is now a lookup call to
the datastore to check for selection of the associated data item record. The
data item record tested so far carries an is_selected boolean, but the code
was written to allow for an is_selected() function.

Removed the experiment with ButtonBehavior. Worked over bindings and events widely. Realized the place to put the call to check_for_empty_selection(), as things are now, is at the bottom of listview.hard_populate(). Cleaned up all of the examples for the changes.

Added ButtonBehavior for use with SelectableItem. Removed use of selection_target mechanism.

Found a much better solution for the relationship between ListAdapter and SelectableItem. Now ListAdapter sets up the binding between SelectableItem on_release event and ListAdapter.handle_selection(). handle_selection(), additionally, now has to check obj.selection_target before calling the new internal _handle_selection(obj) on the selection_target.

Made temporary changes to get the kv template to work with list_cascade_images.py. Will have to review the way list_adapter is set into SelectableItem.

Added Factory register call, and trying to use CompositeListItem in the template for the new thumbnailed cascading lists example.
