In https://github.com/leapdao/leap-core/blob/master/lib/output.js#L93, I'm getting an assertion error when I invoke `calcOutputs` incorrectly. As a user, this gets bubbled up to me as an `AssertionError`, where as I would expect just a normal error. <img width="1425" alt="Screen Shot 2019-04-17 at 16 12 23" src="https://user-images.githubusercontent.com/2758453/56294616-9c94db80-612b-11e9-9cae-bc3d7b1e276b.png">
