Class
    Foam::disabledBoolList

Description
    A trivial structure to use as a boolList replacement when testing
    compilation without using the [] accessors.

    Example,
    \code
    const disableBoolList blockedFace;
    ...

    if (blockedFace.test(facei)) ...    // Good
    if (blockedFace[facei]) ...         // Compile error
    \endcode
