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