  27     \brief Determines if a sequence is a Boost PP seq.
  28
  29     The macro checks that the sequence is a Boost PP seq.
  30     It returns 1 if it is a seq, else if returns 0.

  36     A single set of parentheses, with a single element,
  37     is parsed as a tuple and not a seq. To be parsed as
  38     a seq the input needs to be more than one consecutive
  39     sets of parentheses, each with a single element of data.
