title: Odd and even number comparison helper for Handlebars
body: <p>I am trying to find a way to parse out differently depending array index as odd or even number</p>
  
  <p>I was looking at this <a href="http://assemble.io/helpers/helpers-comparison.html" rel="noreferrer">http://assemble.io/helpers/helpers-comparison.html</a> and hope to find something like this:</p>
  
  <pre><code>{{#each array}}
  {{#if_odd {{@index}}}}
      {{this}} is odd 
  {{else}}
      {{this}} is even
  {{/if_odd}}
  {{/each}}
  </code></pre>
  
  <p>I don't really care about the syntax but hope my idea comes across. Any help? Thanks.</p>
