/**
 * Provides hook implementations for testing the execution order of hooks.
 *
 * By default, these will be called in module order, which is predictable due to
 * the alphabetical module names.
 *
 * Two attributes are used to change the 'test_hook' implementations in module
 * ccc_hook_order_test. One is the ReorderHook attribute which is used to put
 * the \Drupal\ccc_hook_order_test\Hook\CHooks::testHookFirst() first. The other
 * is RemoveHook which is used to remove
 * \Drupal\ccc_hook_order_test\Hook\CHooks::testHookRemoved(). Both of those
 * attributes are declared in \Drupal\ddd_hook_order_test\Hook\DHooks.
 *
 * @see \Drupal\KernelTests\Core\Hook\HookOrderTest::testHookOrder()
 * @see \Drupal\KernelTests\Core\Hook\HookOrderTest::testBothParametersHookOrder()
