    \class QGraphicsSceneLinearIndex
    \brief The QGraphicsSceneLinearIndex class provides an implementation of
    a linear indexing algorithm for discovering items in QGraphicsScene.
    \since 4.6
    \ingroup graphicsview-api
    \internal

    QGraphicsSceneLinearIndex index is default linear implementation to discover items.
    It basically store all items in a list and return them to the scene.
