    This class is served for TreeLayout class.

    All classes inherit this class will have ability to calculate the size of self,
    and report to TreeLayout. TreeLayout will use these data to distribute position.

    The functions declared in this class have unique name meaning. 
    The reason is that the vertical and horizonal direction between BB and Oper is opposited. 
    So we use Leaves and Root to give theme an uniformed concept.
