This class works in conjunction with Psych::Parser to build an in-memory
parse tree that represents a YAML document.

Example:

  parser = Psych::Parser.new Psych::TreeBuilder.new
  parser.parse('--- foo')
  tree = parser.handler.root

See Psych::Handler for documentation on the event methods used in this
class.
