###
# Psych::Stream is a streaming YAML emitter. It will not buffer your YAML,
# but send it straight to an IO.
#
# Here is an example use:
#
# stream = Psych::Stream.new($stdout)
# stream.start
# stream.push({:foo => 'bar'})
# stream.finish
#
# YAML will be immediately emitted to $stdout with no buffering.
#
# Psych::Stream#start will take a block and ensure that Psych::Stream#finish
# is called, so you can do this form:
#
# stream = Psych::Stream.new($stdout)
# stream.start do |em|
# em.push(:foo => 'bar')
# end
#
