 * need a dialog that needs to display a list view control.
 * 
 * This would be the simplest version, in the future it will have a text editor to filter
 * the contents of the list, and it will also support different modes of selection.
 * 
 * For now it just uses an adapter to display the contents of the model data.
 * 
 * It's up to the user to implement the adapter (hmm, perhaps that's where the selection mode logic should be)
