/** \def BOOST_VMD_IS_TUPLE(sequence)

    \brief Tests whether a sequence is a Boost PP tuple.

    The macro checks to see if a sequence is a Boost PP tuple.
    A Boost PP tuple is preprocessor tokens enclosed by a set of parentheses
    with no preprocessing tokens before or after the parentheses.
    
    sequence = a possible tuple

    returns = 1 if the sequence is a Boost PP tuple,
              0 if it is not.
