  /**
   * Add a callback.
   *
   * A callback is called either before a method runs or after. The callback
   * is passed an array of arguments or return value which it can freely
   * manipulate. If the callback runs before the method and sets the arguments
   * array to false (or causes an error), the method will not be run.
   * Callbacks before a method are passed the arguments given when the method
   * was called, while callbacks after a method are passed the return value
   * (in an array) of that method.
   *
   * The callback can receive up to 5 arguments, in this order:
   *
   * - &$arguments - An array of either arguments or a return value.
   * - $name - The name of the hook.
   * - &$object - The object on which the hook caught a method call.
   * - &$function - A callback for the method call which was caught. Altering
   *   this will cause a different function/method to run.
   * - &$data - An array in which callbacks can store data to communicate with
   *   later callbacks.
   *
   * A hook is the name of whatever method it should catch. A hook can also
   * have an arbitrary name, but be wary that it may already exist and it may
   * result in your callback being falsely called. In order to reduce the
   * chance of this, always use a plus sign (+) and your component's name to
   * begin arbitrary hook names. E.g. "+com_games_player_bonus".
   *
   * If the hook is called explicitly, callbacks defined to run before the
   * hook will run immediately followed by callbacks defined to run after.
   *
   * A negative $order value means the callback will be run before the method,
   * while a positive value means it will be run after. The smaller the order
   * number, the sooner the callback will be run. You can think of the order
   * value as a timeline of callbacks, zero (0) being the actual method being
   * hooked.
   *
   * Additional identical callbacks can be added in order to have a callback
   * called multiple times for one hook.
   *
   * The hook "all" is a pseudo hook which will run regardless of what was
   * actually caught. Callbacks attached to the "all" hook will run before
   * callbacks attached to the actual hook.
   *
   * Note: Be careful to avoid recursive callbacks, as they may result in an
   * infinite loop. All methods under $_ are automatically hooked.
   *
   * @param string $hook The name of the hook to catch.
   * @param int $order The order can be negative, which will run before the method, or positive, which will run after the method. It cannot be zero.
   * @param callback The callback.
   * @return array An array containing the IDs of the new callback and all matching callbacks.
   * @uses \SciActive\Hook::sortCallbacks() To resort the callback array in the correct order.
