Class
    Foam::slicedFvsPatchField

Description
    Specialization of fvsPatchField which creates the underlying
    fvsPatchField as a slice of the given complete field.

    The destructor is wrapped to avoid deallocation of the storage of the
    complete fields when this is destroyed.

    Should only used as a template argument for SlicedGeometricField.
