Oddly, this doesn't exit with a nonzero status.  Gotta love gulp.

Brian, any idea what's up here?

Haha, I think I see what is happening. I added a console.log right before the line where this errors to see what it is failing on and it is just hundreds of lines of

```
The most basic element of a scope expression                                                                                                                          
AnyOf objects will evaluate to true if any subexpressions are true                                                                               
```                                                                                                          
              
I think we have an infinite loop on our hands! I'll see if I can fix it.

Indeed [0] is an infinite loop. As I understood it, json-schema-ref-parser was supposed to eliminate infinite loops somehow, but it has been a while since I looked last.
