Class
    Foam::surfaceWriters::mydebugWriter

Description
    A surfaceWriter for special purpose debugging.
    Its definition and behaviour are subject to change at any time.

    \verbatim
    formatOptions
    {
        debug
        {
            merge   true;
            write   true;
        }
    }
    \endverbatim

    Format options:
    \table
        Property    | Description                           | Required | Default
        commsType   | scheduled/nonBlocking/buffered        | no  | scheduled
        merge       | Enable geometry/field merging         | no  | true
        write       | Write file(s)                         | no  | false
        narrow      | Communicate with narrowed values      | no  | false
    \endtable

Note
    Disabling geometry/field merging (in parallel) implicitly deactivates
    writing as well.

    Output files (if any) are written as boundaryData (binary + header).
