Errors with large data structures became harder to read #108
Description
I use expound in edna and I noticed that errors in 0.7.1 were harder to read than in 0.7.0 when they occur inside a large outer data structure. In 0.7.0, it points to the specific part of the data structure first:
Exception in thread "main" java.lang.Exception: -- Syntax error -------------------
[...

In 0.7.1, it prints the entire data structure first, and you have to scroll (sometimes far) down to see it eventually point to the specific part of the data structure where the error is:
Exception in thread "main" java.lang.Exception: -- Spec failed --------------------

I posted a code example and the output of both versions here https://gist.github.com/oakes/dbc902e8fb077d6430fa0909cf4d7272
