+
+ \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.
