YAML::PullParser
A pull parser allows parsing a YAML document by events.
When creating an instance, the parser is positioned in
the first event. To get the event kind invoke kind.
If the event is a scalar you can invoke value to get
its string value. Other methods like tag, anchor
and scalar_style let you inspect other information from events.
Invoking read_next reads the next event.
