    make simulated animations part of the animation engine
    
    Wiring up and creating required classes for simulated
    animations to be part of the animation engine.
    
    Creating a new animation node AnimationSimulationNode
    for simulated animations and SimulatedAnimation class
    that inherits from NumberAnimation in the animation
    factory.
    
    Also, this commit makes it possible to have two box2d
    animation effects in parallel with -with previous-
    option

    Add Shape mbIsForeground flag and getters and setters for it
    
    mbIsForeground is a flag that is set if a shape is known to not belong
    to the foreground.
    
    It is set to false while shapes are being imported and the shape
    belongs to the master slide or is a group shape, right now.

    adding XShapeToShapeMapSharedPtr getter to ShapeManager
    
    Refactoring XShapeHash in layermanager as XShapeToShapeMap
    and XShapeHash in targetpropertiescreator as XShapeToNamedValuesMap.
    This refactoring describes what the types are more clearly and
    stops violating one define rule in the desired implementation.
    
    In layer manager getting XShapeToShapeMap ready to be passed around
    changing it to be a shared pointer.
    
    And adding getter getXShapeToShapeMap to ShapeManager to enable
    Animation::start() to access Shapes and XShapes of the current
    slide.

    box2d tools: initial work for physics based animation effects
    
    Two new classes for managing box2d bodies(b2Body) and box2d worlds(b2World)
    
    ::box2d::utils::Box2DBody :
    Since b2Body has a private constructor, it is forbidden to make a shared_ptr
    out of it.
    When there are multiple parallel physics based animation effects going on,
    it will be useful to share b2Body pointers around.
    This class will help with that and also has get methods that return LO types
    instead of box2d ones.
    
    ::box2d::utils::Box2DWorld :
    A class that manages b2World with convenient functions that will be needed
    during animation effects.
