Class
    Foam::patchProbes

Description
    Set of locations to sample at patches

    Call write() to sample and write files.
    - find nearest location on nearest face
    - update *this with location (so header contains 'snapped' locations
    - use *this as the sampling location

    Example of function object specification:
    \verbatim
    patchProbes
    {
        type            patchProbes;
        libs            (sampling);

        // Name of the directory for probe data
        name            patchProbes;

        // Patches to sample (wildcards allowed)
        patches         (".*inl.*");

        // Write at same frequency as fields
        writeControl    writeTime;
        writeInterval   1;

        // Fields to be probed
        fields          (p U);

        // Locations to probe. These get snapped onto the nearest point
        // on the selected patches
        probeLocations
        (
            ( -100 0 0.01 )      // at inlet
        );
    }
    \endverbatim
