示例1: ConnectMultiheadedTrains

* Link front and rear multiheaded engines to each other
* This is done when loading a savegame
*/

* sequential-matching: Trains shall be arranged to look like <..>..<..>..<..>..
* bracket-matching: Free vehicle chains shall be arranged to look like ..<..<..>..<..>..>..
*
* Note: Old savegames might contain chains which do not comply with these rules, e.g.
* - the front and read parts have invalid orders
* - different engine types might be combined
* - there might be different amounts of front and rear parts.
*
* Note: The multiheaded parts need to be matched exactly like they are matched on the server, else desyncs will occur.
* This is why two matching strategies are needed.
