   *   an `is` property to specify the element name. Other properties populate
   *   the element prototype. The `properties`, `observers`, `hostAttributes`,
   *   and `listeners` properties are processed to create element features.
   * @return {!Object} Returns a custom element class for the given provided
   *   prototype `info` object. The name of the element if given by `info.is`.
