title: Rally List all Features query
body: <p>I'm trying to find a complete list of all Features available (I don't have many, just tinkering).  I've tried a number of different ways, but I can't seem to find the correct syntax for referencing the Features.</p>
  
  <p>First attempt:</p>
  
  <pre><code>type: 'PortfolioItem/Feature'
  key: 'Feature"
  fetch: 'Name'
  </code></pre>
  
  <p>This resulted in an error.  I then tried:</p>
  
  <pre><code>type: 'hierarchicalrequirement'
  key: 'features'
  fetch: 'Name,Parent.Name'
  </code></pre>
  
  <p>Also an error.</p>
  
  <p>I've listed the type as PortfolioItem, PortfolioItem/Feature, and Feature.  I've fetched for Name, formattedID, Parent.Name, parent.FormattedID, and maybe a few more. I can't seem to find where to search to just see a list of all of the features available. Please advise.</p>
