CHOMPStation2/code/ATMOSPHERICS/components/trinary_devices/mixer.dm
Leshana edd1cfd316 Eliminated duplicate code in trinary components. 
- Consolidate common functions into trinary_base
- The only real difference in atmos_init was which direction each node would connect in.  Delegated that to an overridable proc, and the rest can be consolidated. Same story for update_underlays()
- Used similar patterns on tvalves which also are trinary even tho they are not subtyes of trinary (for some reason)
