    \brief The ActivityIndicator component visually indicates that a task of
    unknown duration is in progress, e.g. busy indication, connection in progress
    indication, etc.

    Note: for time consuming JavaScript operations use WorkerScript, otherwise no
    UI interaction will be possible and the ActicityIndicator animation will freeze.

    Example:
    \qml
    Item {
        ActivityIndicator {
            id: activity
        }

        Button {
            id: toggleActive
            text: (activity.running) ? "Deactivate" : "Activate"
            onClicked: activity.running = !activity.running
        }
    }
    \endqml

    /*!
       Presents whether there is activity to be visualized or not. The default value is false.
       When activated (set to true), an animation is shown indicating an ongoing activity, which
       continues until deactivated (set to false).
