title: Require at least one of two fields using vee-validate on VueJS 2.0
body: <p>I am using <a href="http://vee-validate.logaretm.com/" rel="noreferrer">vee-validate</a> and I have two fields; one for <strong>Home Phone</strong> and one for <strong>Cell Phone</strong>. I don't need to make both <em>'required'</em> for the rules, but what I need is at least one of these required. </p>
  
  <p>So, my question, is it possible to set up a rule that checks both fields for input in at least one of them?</p>
