Instead of maintaining 3 different states, each tied to a subset of data, maintaing a single state that represents all the data. Individual subset data is invalidated in rare cases and these invalidates are tightly tied to the UI. This also allows us to add new data to the model, without worring about classifying the data into a subset. Bug: 34112546 Change-Id: Id9cb273de35b79e84a2ef8d6556fcf1e72fb4b75
