ricky 68a1bec062 [ASTextNode2] Make some ASTextNode2 layout files public (#1939)
* Trying to make ASTextLinePositionModifier public

* d’oh

* be a little more restrictive on the files we pull into the pod

* Never mind, I guess we need all of these

* update the project file as well

* try this again

* I think this will work this time.
