Class
    Foam::patchToPatches::inverseDistance

Description
    Class to generate patchToPatch coupling geometry. Couples a face to the
    opposite face onto which its centre-normal ray projects, plus the immediate
    neighbours to that opposite face. The proportion of contribution from the
    different faces is calculated using inverse distance weighting.
