title: How to run Dropzone processQueue() when not initiating programmatically?
body: <p>Im trying to initiate dropzone by adding the class to the form like this :</p>
  
  <pre><code>&lt;form class="dropzone ng-pristine ng-valid dz-clickable" id="photoDropzoneDiv" action="/panel/vehicles/3/photos" accept-charset="UTF-8" method="post"&gt;
  </code></pre>
  
  <p>Now dropzone works. Next I set dropzone not to auto process the queue :</p>
  
  <pre><code>Dropzone.options.photoDropzone = {
      paramName: "file", // The name that will be used to transfer the file
      maxFilesize: 5, // MB
      autoProcessQueue: false,
      parallelUploads: 500,
      acceptedFiles: '.jpg,.jpeg,.JPEG,.JPG,.png,.PNG',
      addRemoveLinks: true,
      init: function(file, done) {
          this.on("queuecomplete", function(file) {
              this.removeAllFiles();
          });
      }
  };
  </code></pre>
  
  <p>Now when I call the processQueue like this :</p>
  
  <pre><code>photoDropzone.processQueue();
  </code></pre>
  
  <p>It says <code>Uncaught TypeError: photoDropzone.processQueue is not a function</code>. How can I fix this?</p>
