Sliding double doors

This is a set of double doors that slides when one of them is touched. Put the controller in the ROOT PRIM, this essentially relays the fact that it has been touched to both doors at the same time so they should open at the same time. Make one door that has a positive open_by amount and another that has a negative amount. Can also change the direction of opening by putting a different axis in.

//essentially just relays a linked message.
