    * Use `Polymer.PaperInputBehavior` to implement inputs with `<paper-input-container>`. This
    * behavior is implemented by `<paper-input>`. It exposes a number of properties from

    * template.
    *
    * The input element can be accessed by the `inputElement` property if you need to access
    * properties or methods that are not exposed.
