   *   An array of buttons that are provided by this plugin. This will
   *   only be used in the administrative section for assembling the toolbar.

   *   contain an array of button properties, including:
   *   - label: A human-readable, translated button name.
   *   - image: An image for the button to be used in the toolbar.
   *   - image_rtl: If the image needs to have a right-to-left version, specify
   *     an alternative file that will be used in RTL editors.
   *   - image_alternative: If this button does not render as an image, specify
   *     an HTML string representing the contents of this button.
   *   - image_alternative_rtl: Similar to image_alternative, but a
   *     right-to-left version.
   *   - attributes: An array of HTML attributes which should be added to this
   *     button when rendering the button in the administrative section for
   *     assembling the toolbar.
   *   - multiple: Boolean value indicating if this button may be added multiple
   *     times to the toolbar. This typically is only applicable for dividers
   *     and group indicators.
