    \brief The Repeater item allows you to repeat a component based on a model.

    The Repeater item is used when you want to create a large number of
    similar items.  For each entry in the model, an item is instantiated
    in a context seeded with data from the model.  If the repeater will
    be instantiating a large number of instances, it may be more efficient to
    use one of Qt Declarative's \l {xmlViews}{view items}.

    The model may be either an object list, a string list, a number or a Qt model.
    In each case, the data element and the index is exposed to each instantiated
    component.  
    
    The index is always exposed as an accessible \c index property.
    In the case of an object or string list, the data element (of type string
    or object) is available as the \c modelData property.  In the case of a Qt model,
    all roles are available as named properties just like in the view classes. The
    following example shows how to use the index property inside the instantiated
    items.

    \snippet doc/src/snippets/declarative/repeater-index.qml 0

    \image repeater-index.png

    Items instantiated by the Repeater are inserted, in order, as
    children of the Repeater's parent.  The insertion starts immediately after
    the repeater's position in its parent stacking list.  This is to allow
    you to use a Repeater inside a layout.  The following QML example shows how
    the instantiated items would visually appear stacked between the red and
    blue rectangles.

    The repeater instance continues to own all items it instantiates, even
    if they are otherwise manipulated.  It is illegal to manually remove an item
    created by the Repeater.

    The Repeater item is used when you want to create a large number of
