Added defined switches, fixed bugs

Browse Source 
+Added pre-defined switches so they dont have to be generated. Unrecognised switches models are still automatically resolved and their new definitions are saved for later use
+Added .multiply, .toPrecission and .rotate functions in the Vector3 class
*Improved switches to normal tracks connections
*Improved switches-related error handling
