Detailed Description

Determines a mapping between patch face centres and mesh cell or face centres and processors they're on.

If constructed from dictionary:

    // Region to sample (default is region0)
    sampleRegion region0;

    // What to sample:
    // - nearestCell         : sample cell containing point
    // - nearestOnlyCell     : nearest sample cell (even if not containing
    //                         point)
    // - nearestPatchFace    : nearest face on selected patch
    // - nearestPatchFaceAMI : nearest face on selected patch
                               - patches need not conform
                               - uses AMI interpolation
    // - nearestFace         : nearest boundary face on any patch
    // - nearestPatchPoint   : nearest patch point (for coupled points
    //                         this might be any of the points so you have
    //                         to guarantee the point data is synchronised
    //                         beforehand)
    sampleMode nearestCell;

    // If sampleMode is nearestPatchFace : patch to find faces of
    samplePatch movingWall;

    // If sampleMode is nearestPatchFace : specify patchgroup to find
    // samplePatch and sampleRegion (if not provided)
    coupleGroup baffleGroup;

    // How to supply offset (w.r.t. my patch face centres):
    // - uniform : single offset vector
    // - nonuniform : per-face offset vector
    // - normal : using supplied distance and face normal
    offsetMode uniform;

    // According to offsetMode (see above) supply one of
    // offset, offsets or distance
    offset  (1 0 0);

Note: if offsetMode is normal it uses outwards pointing normals. So supply a negative distance if sampling inside the domain.

Note: Storage is not optimal. It temporary collects all (patch)face centres on all processors to keep the addressing calculation simple.
