  <h1> Angular 2 Animation State Transition Test </h1>
  <p> Trying to replicate old animation API behaviour of animationBuilder.css().setToFromStyles() etc </p>
  <p> The old animations API used to play from CURRENT style. Now it starts from beginning of state. </p>
  <p> i.e. A state transition of 'open' -> 'closed' -> 'open' before the 'closed' animation completed<br/> would result in
      a FULL 'closed' to 'open' transition instead of a PARTIAL transition (from whatever css <br/>styles were currently applied 
      at the time of when the second 'open' state transition occurred.</p>
  <h3> As of RC3 I can't figure this out with the new API syntax. </h3>
  <h4> Instructions:</h4>
  <li> Click 'Toggle State' to fade out the component over 3 seconds (i.e. change state to 'closed')</li>
  <li> Click 'Toggle State' again after ~1.5 seconds, i.e. change state back to 'open'</li>
  <li> <b>Expect:</b> Nice fadeout/fadein from {opacity: 1} to {opacity: 0.5} back to {opacity: 1}</li>
  <li> <b>Actual Result:</b> Fadeout for 1.5s then harsh fadein from 0 opacity</li>
      <a (click)="beginAnim()">Toggle State</a>
    <div class="dummyComponent" @fadeInOut="state">
    <div>Current State: <b>{{state}}</b></div>
