title: JSON feed object/array specify root name?
body: <p>I just discovered and I am very excited about this product... I've had some luck getting my calendar populated... however, I need some more info I cannot explicitly find in the documentation... How do I point to the root JSON object key name "events" if I return an object instead of an array?</p>
  
  <p>If I return an object from SQL like shown here, the events will not be rendered:</p>
  
  <p><code>{ "events": [ { "id": 434, "title": "Slot 434", "start": "2020-05-20T09:00:00", }, { "id": 435, "title": "Slot 435", "start": "2020-05-20T09:30:00", } ] }</code></p>
  
  <p>However, if I return an object from SQL like this, they WILL render.</p>
  
  <p><code>[ { "id": 434, "title": "Slot 434", "start": "2020-05-20T09:00:00", }, { "id": 435, "title": "Slot 435", "start": "2020-05-20T09:30:00", } ]</code></p>
  
  <p>When using a JSON feed, how to I specify the object root name?</p>
  
  <p>I should mention I am using the events url object:</p>
  
  <pre><code>events: {
    url: '[OUR INTERNAL API AND MSSQL SERVER THING]',
    method: 'POST',
    // extraParams: {
    //   custom_param1: 'something',
    //   custom_param2: 'somethingelse'
    // },
    failure: function () {
      alert('there was an error while fetching events!');
    },
    // color: 'yellow',   // a non-ajax option
    // textColor: 'black' // a non-ajax option
  },
  </code></pre>
