Class
    Foam::SlicedGeometricField

Description
    Specialization of GeometricField which holds slices of given complete
    fields in a form that they act as a GeometricField.

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

    SlicedGeometricField can only be instantiated with a valid form of
    SlicedPatchField to handle the slicing and storage deallocation of the
    boundary field.
