Class
    Foam::surfaceReader

Description
    Abstract base class for surface readers with fields.

    Some readers support different input options, these are typically
    specified as 'readOptions' in the containing dictionary.

    \verbatim
    readOptions
    {
        default
        {
            verbose     false;
        }

        ensight
        {
            masterOnly  false;
        }
    }
    \endverbatim
