Allow two pig.json files to reference each other without Maximum call stack size exceeded error

[KylePalko]

I ran into this issue when I had an API Server that I wanted to spin up with my App Server (and vice versa)

/app/pig.json

{
  "include": {
    "../api/pig.json": "api"
  }
}

/api/pig.json

{
  "include": {
    "../app/pig.json": "app"
  }
}

This will cause the error below

RangeError: Maximum call stack size exceeded

Btw, thanks for this. It's exactly what I needed! I may try to get involved in the project once I understand the context. I wouldn't mind making this change if you'd like.

Hi!

Sorry, I'm not maintaining pig actively at the moment. You should try using docker-compose or similar tool instead. pig has last been tested with docker 1.4.0 (or was it 1.5.0).

Ah, okay. Thanks. Was there a specific reason you stopped supporting it? It has some added features that Docker Compose doesn't yet have.
