This handler will capture an event and record the event. Recorder events are available vial #events.

For example:

recorder = Psych::Handlers::Recorder.new
parser = Psych::Parser.new recorder
parser.parse '--- foo'

recorder.events # => [list of events]

# Replay the events

emitter = Psych::Emitter.new $stdout
recorder.events.each do |m, args|
  emitter.send m, *args
end
