/** \def BOOST_VMD_IS_ARRAY(sequence)
\brief Determines if a sequence is a Boost PP array.
The macro checks that the sequence is a Boost PP array.
It returns 1 if it is an array, else if returns 0.
sequence = a possible Boost PP array.
returns = 1 if it is an array, else returns 0.
The macro will generate a preprocessing error if the input
is in the form of an array but its first tuple element, instead
of being a number, is a preprocessor token which VMD cannot parse,
as in the example '(&2,(0,1))' which is a valid tuple but an invalid
array.
