Start of new N-Demo "Terminal"

The new N-Demo layout measures 140 x 16cm and will have 7 logical blocks.

I decided to use Peco Streamline Code 55 after I had seen a very nice layout at the MGV.

The Relay motor is too weak for setting the double crossing so I will use also for this layout the servo solution.
The servos will be controlled by the MGV136/137 and the RailCom/Current sens by the OpenDCC BiDiGBM.
