Added data=ListProperty([]) to ListAdapter so that updates will fire when data changes (previously data was only set in Adapter as data = ObjectAdapter()). Added tests for resetting data or data elements.
Added KIVY_USE_DEFAULTCONFIG = 1 so that Kivy tests are not affected by local configuration.
Fixed docs.
Added a list example that illustrates adding and changing data on a timer.
