title: Grabing hashtagged word from a string using regex
body: <p>Well, as the title says... I want to grab a certain word that is hashtagged in a string.</p>
  
  <p>Example:
  <em>This is a string that <strong>#contains</strong> a hashtag!</em></p>
  
  <p>I want to pick out the word <strong>contains</strong> from the string as a new string.</p>
  
  <p>I can imagine that this is a very simple problem, but I really can't get it to work.</p>
