/** \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.
