          Proxies a call to :meth:`BreakpointGraph._BreakpointGraph__delete_all_bgedges_between_two_vertices` method.
  
          :param vertex1: a first out of two vertices edges between which are to be deleted
          :type vertex1: any python hashable object. :class:`bg.vertex.BGVertex` is expected
          :param vertex2: a second out of two vertices edges between which are to be deleted
          :type vertex2: any python hashable object. :class:`bg.vertex.BGVertex` is expected
          :return: ``None``, performs inplace changes
