Visual evolution of a three-dimensional morphological snake.
    
    Parameters
    ----------
    msnake : MorphGAC or MorphACWE instance
        The morphological snake solver.
    fig: object, optional
        Handles to actual figure.
    levelset : array-like, optional
        If given, the levelset of the solver is initialized to this. If not
        given, the evolution will use the levelset already set in msnake.
    num_iters : int, optional
        The number of iterations.
    animate_ui : bool, optional
        Show the animation interface
    animate_delay : int, optional
        The number of delay between frames.
