-`<hero-animation>` is a shared element animation that scales and transform an element such that it
-appears to be shared between two pages. Use this in `<neon-animated-pages>`. The source page
-should use this animation in an 'exit' animation and set the `fromPage` configuration property to
-itself, and the destination page should use this animation in an `entry` animation and set the
-`toPage` configuration property to itself. They should also define the hero elements in the
-`sharedElements` property (not a configuration property, see
-`Polymer.NeonSharedElementAnimatableBehavior`).
-
-Configuration:
-```
-{
-  name: 'hero-animation',
-  id: <shared-element-id>,
-  timing: <animation-timing>,
-  toPage: <node>, /* define for the destination page */
-  fromPage: <node>, /* define for the source page */
-}
