Verify that cell2cellFace on periodic meshes should be derived from Interpolate (face→cell), not from ComposeFiltered. The compose-based approach cannot correctly distinguish face-neighbors from non-face-neighbors when all cells share all nodes (as on 2×2 doubly-periodic or 2×2×2 triply-periodic meshes).

The correct cell2cellFace derivation is tested in "Periodic 2x2: cell2face from Interpolate" and "Periodic 2x2x2: face interpolation" tests above.
