title: Check if a string contains an email address?
body: <p>How can I check to verify that a given string contains an email address.</p>
  
  <p>The email address would be included with a lot of other text, as well.</p>
  
  <p>Also, not looking to necessarily strictly validate the email address itself. More so just wanting to make sure that <code>a@b.xyz</code> is present.</p>
  
  <p>Example string:</p>
  
  <pre><code>Overall I liked the service, but had trouble using the widget generator.
  
  Want more info? You can contact me at bob@example.org.
  </code></pre>
  
  <p>Plain javascript is fine, but I do happen to be using jQuery, so if there's some sort of helper function that makes this easier...go for it.</p>
