\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.
