bool $lineStart
True if the open char appeared at the start of the input line.
breakSyntax( $openingCount=false)

int $count
Number of opening characters found (number of "=" for heading)
string $savedPrefix
Saved prefix that may affect later processing, e.g.
string $open
Opening character (\n for heading)
string $close
Matching closing character.
__construct( $data=[])
PPDPart [] $parts
Array of PPDPart objects describing pipe-separated parts.
