$this->stopwatch->start('processing-file');
$this->stopwatch->stopSection('parsing');

All events that don't belong to any named section are added to the special section
``__root__``. This way you can get all stopwatch events, even if you don't know
their names::

foreach($this->stopwatch->getSectionEvents('__root__') as $event) {
echo (string) $event;
}
