    /// A `Group` controls one or more `Container`-s (usually `Clip`-s,
    /// but it can also control other `Group`-s). Its children must share
    /// the same `Timeline`, but can otherwise lie in separate `Layer`-s
    /// and have different timings.
    ///
    /// To initialise a group, you may want to use `Container::group`,
    /// and similarly use `GESContainerExt::ungroup` to dispose of it.
    ///
    /// A group will maintain the relative `TimelineElement:start` times of
    /// its children, as well as their relative layer `Layer:priority`.
    /// Therefore, if one of its children has its `TimelineElement:start`
    /// set, all other children will have their `TimelineElement:start`
    /// shifted by the same amount. Similarly, if one of its children moves to
    /// a new layer, the other children will also change layers to maintain the
    /// difference in their layer priorities. For example, if a child moves
    /// from a layer with `Layer:priority` 1 to a layer with priority 3, then
    /// another child that was in a layer with priority 0 will move to the
    /// layer with priority 2.
    ///
    /// The `Group:start` of a group refers to the earliest start
    /// time of its children. If the group's `Group:start` is set, all the
    /// children will be shifted equally such that the earliest start time
    /// will match the set value. The `Group:duration` of a group is the
    /// difference between the earliest start time and latest end time of its
    /// children. If the group's `Group:duration` is increased, the children
    /// whose end time matches the end of the group will be extended
    /// accordingly. If it is decreased, then any child whose end time exceeds
    /// the new end time will also have their duration decreased accordingly.
    ///
    /// A group may span several layers, but for methods such as
    /// `TimelineElementExt::get_layer_priority` and
    /// `TimelineElementExt::edit` a group is considered to have a layer
    /// priority that is the highest `Layer:priority` (numerically, the
    /// smallest) of all the layers it spans.
