The dump method, when supplied with an array, will do its best
to convert the array into friendly YAML. Pretty simple. Feel free to
save the returned string as tasteful.yaml and pass it around.
Oh, and you can decide how big the indent is and what the wordwrap
for folding is. Pretty cool -- just pass in 'false' for either if
you want to use the default.
Indent's default is 2 spaces, wordwrap's default is 40 characters. And
you can turn off wordwrap by passing in 0.
