An array-like container for data for use in UI components.
When a ui.data.ActiveList (e.g. Map.layers()) is updated, the component it belongs to is updated as well. For example, Map.layers().add(myLayer) will add myLayer as a layer on the map.

It can be initialized with a list. Actions like adding to the `ActiveList` directly reflect in the UI. For instance, `Map.layers().add(myLayer)` adds a layer to the map. The constructor `ui.data.ActiveList(list)` creates an `ActiveList` object, and it allows the input parameter list, which is an optional list used to initialize the container.\n"]]
