A proof of concept for a modular Metro station.

Place Metro entrances and platforms separately and connect them with pedestrian tunnels.

This is only a proof of concet. There are still some issues and i am planning to improve the assets.

Issues:
- The Metro platform needs a free 1x1 square at the side of the road.
- You can only connect a pedestrian tunnel to the front connector of the Metro entrance, when you connect a tunnel to the back
connector first.
- When the ground is not flatt, the tunnel connector can get disconnected from the asset, and pedestrians cannot pass.
Use Terraform Tool.
-Because tunnels have to be placed min. -12 underground thy go underneath the platform and not above, like in a real metro.
-Metro entrances appear as actual (non functional) Stations, because they are in the Metro Category.

Plans:
- Move the Metro Entrances to Beatification (Only possible with a textured model).
- Make custom underground pedestrian passageway, that can be placed above -12.
- Add multi-track platforms.
