/**
 * Provides a "Global Slider" Price Alterator for BeeHotel.
 *
 * Because the plugin manager class for our plugins uses annotated class
 * discovery, Price Alterators only needs to exist within the
 * Plugin\PriceAlterator namespace, and provide a PriceAlterator
 * annotation to be declared as a plugin. This is defined in
 * \Drupal\beehotel_pricealterator\PriceAlteratorPluginManager::__construct().
 *
 * The following is the plugin annotation. This is parsed by Doctrine to make
 * the plugin definition. Any values defined here will be available in the
 * plugin definition.
 *
 * This should be used for metadata that is specifically required to instantiate
 * the plugin, or for example data that might be needed to display a list of all
 * available plugins where the user selects one. This means many plugin
 * annotations can be reduced to a plugin ID, a label and perhaps a description.
 *
 *
 *  The weight Key is the weight for this alterator.
 * Legenda for the 'weight' key:
 * -9999 : heaviest, to be used as very first (reserved)
 * -9xxx : heavy, to be used as first (reserved)
 *     0 : no need to be weighted
 *  1xxx : allowed in custom modules (@TODO)
 *  xxxx : everything else
 *  9xxx : light, to be used as last (reserved)
 *  9999 : lightest, to be used as very last (reserved)
 *
 * @PriceAlterator(
 *   description = @Translation("Slide globally price up and down"),
 *   id = "GlobalSlider",
 *   provider = "beehotel_pricealterator",
 *   status = 1,
 *   type = "optional",
 *   weight = 9999,
 * )
