/**
 * Defines a base CKEditor plugin implementation.
 *
 * No other CKEditor plugins can be internal, unless a different CKEditor build
 * than the one provided by Drupal core is used. Most CKEditor plugins don't
 * need to provide additional settings forms.
 *
 * This base class assumes that your plugin has buttons that you want to be
 * enabled through the toolbar builder UI. It is still possible to also
 * implement the CKEditorPluginContextualInterface (for contextual enabling) and
 * CKEditorPluginConfigurableInterface interfaces (for configuring plugin
 * settings).
 *
 * NOTE: the Drupal plugin ID should correspond to the CKEditor plugin name.
