.. class:: refine_degree_1

    Refine multiple degree 1-vertices connected to the same vertex.


    Cells consisting entirely of degree 1 vertices, where all vertices have the
    same neighbour, with the same type of edge, will be split into trivial cells.
    Either `RefinementResult::Never` or `RefinementResult::Unchanged` will be returned and the appropriate automorphisms are reported.

    The class is DefaultConstructible.
