Add #to_ary to Diff::LCS::Change and Diff::LCS::ContextChange

[knu]

It would be quite handy if you could write as follows:

Diff::LCS.sdiff(a, b).each do |action, (old_position, old_element), (new_position, new_element)|
  case action
  when '!'
    # replace
  when '-'
    # delete
  when '+'
    # insert
  end
end

Simple but effective. Can I ask that you add a little documentation for this particular use-case? I can see my way to making a release on the weekend.

@halostatue I added a paragraph to the rdoc of Diff::LCS.sdiff. Feel free to correct it as necessary!

Thanks!
