title: How to find element on page using ruby
body: <p>I use Ruby's PageObject for testing and have an element </p>
  
  <pre><code>button(:showLocs,:title=&gt;"Show All Items")
  </code></pre>
  
  <p>in my page-class.</p>
  
  <p>What method I should use to check that page includes this object?
  I think that it should look as </p>
  
  <pre><code>if self.showLocs_element.find then #doing smth
  </code></pre>
