Class
    Foam::attachPolyTopoChanger

Description
    This class is derived from polyMesh and serves as a tool for
    statically connecting pieces of a mesh by executing the mesh
    modifiers and cleaning the mesh.

    The idea is that a mesh can be built from pieces and put together
    using various mesh modifiers (mainly sliding interfaces) which are
    not needed during the run.  Therefore, once the mesh is assembled
    and mesh modification triggered, the newly created point, face and
    cell zones can be cleared together with the mesh modifiers thus
    creating a singly connected static mesh.

    Note:
    All point, face and cell zoning will be lost!  Do it after
    attaching the parts of the mesh, as the point, face and cell
    numbering changes.
