\brief Determines if a sequence is a Boost PP seq.
The macro checks that the sequence is a Boost PP seq.
It returns 1 if it is a seq, else if returns 0.
sequence = a possible Boost PP seq
returns = 1 if it a seq, else returns 0.
A single set of parentheses, with a single element,
is parsed as a tuple and not a seq. To be parsed as
a seq the input needs to be more than one consecutive
sets of parentheses, each with a single element of data.
