Nash testing infrastructure

[i4ki]

• Builtin testing infrastructure?
• Go API for testing (like we did in [klb])(https://github.com/NeowayLabs/klb/blob/master/tests/lib/nash/nash.go)

I'm inclined to add both the Go API and some nice way for people test theirs shell scripts without the need of using Go.

I think both ideas are good. Go infra helps us test to catch deep nash bugs and the nash infrastructure would be great to test properly the scripts. I would just break in two completely separated issues for discussion and implementation.

I agree with @katcipis on treating things separately. Also I would give a higher priority to the builtin test infrastructure.
