-`core-list` displays a virtual, 'infinite' list. The template inside the 
-`core-list` element represents the dom to create for each list item. The
-`data` property specifies an array of list item data. The `height` property
-represents the height of a list item.
-
-By default, the list supports selection via tapping. Styling the selection 
-should be done via binding. The `selectedProperty` property is set on the 
-list view data for each selected item.
-
-`core-list` manages a viewport of data based on the current scroll position.
-For performance reasons, not every item in the list is rendered at once.
