Node engine

[goodmind]

error repdeps@0.3.1: The engine "node" is incompatible with this module. Expected version "8.9.4". Got "11.7.0"

@goodmind I updated chai, nyc and yargs and published version 0.3.2.

I hope this solves the problem.

@joebowbeer, you probably should also remove

"engines": {
    "node": "8.9.4"
  },

@goodmind doik! I looked for that the first time but didn't see it. Curious that it is building on node 10 now on travis...

I'll do this soon.

Fixed in 0.3.3 - which builds on node 11.9.0 in travis
