Control Lionel Switch Track from a raspbery pi. Used for switching relays on a https://sequentmicrosystems.com/products/raspberry-pi-relays-stackable-card board attached to a raspbery pi.
Lionel switch remote switch track uses a momentary switches. One activates switch track to through. The other activates to bypass. We will use a set of relays. We will turn on / off a relay to act like a momentary switch.
The application will facitage as a service for both command line and eventually support webapi.
It will hold the current last know computer controlled state.

Default mapping used for the project.
| SWITCH | RELAY NUMBER | ACTION |
|---|---|---|
| Switch 1 | relay 0 | through |
| Switch 1 | relay 1 | bypass |
| Switch 2 | relay 2 | through |
| Switch 2 | relay 3 | bypass |
| Switch 3 | relay 4 | through |
| Switch 3 | relay 5 | bypass |
| Switch 4 | relay 6 | through |
| Switch 4 | relay 7 | bypass |
switchTrack(SwitchNumber,Through)
switchTrack(SwitchNumber,bypass)
switchTrack(1)Through
switchTrack(1,False) bypasses
