There are already two ways to write Refs: `Ref("ResourceName")` and `Ref(ResourceObject)`

Is there such a test for those? -> yes I found one and added another two in fungusakafungus/troposphere#1

But it seems like an overkill.

Instead, I would like to have the original JSON files in the repo somewhere and a naming scheme for *.py in examples/, so we can compare generated with original in test_examples. Would be a general way to catch regressions and to test that implicit Refs do not break anything.
