title: Youtube_It example code draws Argument Error
body: <p>I wrote some basic code to try and get the library working. I am operating on Windows 7, and I just installed the youtube_it gem and attempted to run some example code from the readme, however, I received a puzzling ArgumentError. Here is the code that I tried to run:</p>
  
  <pre><code>#Test YouTube Ruby file. 
  require 'youtube_it'
  client = YouTubeIt::Client.new(:dev_key =&gt; "my developer key here)
  client.videos_by(:query =&gt; "penguin", :max_results =&gt; 1)
  client.videos.each do |video|
    video.title
    video.video_id
  end
  </code></pre>
  
  <p><code>For reference, the error received was this: C:/RailsInstaller/Ruby1.9.3/lib/rubygems/1.9.1/gems/youtube_it-2.3.1/lib/youtube_it/request/video_upload.rb:265: in 'videos' wrong number of arguments (0 for 1) (ArgumentError).</code></p>
  
  <p>Any input as to how I could go about troubleshooting this would be great. </p>
