Hey Thomas. Thanks for trying. can't stress how excited I am.

Okay, I fixed the node issues at 2.1.x branch:
require('coffee-script/register');

    Engine = require('./engine/src/Engine.coffee');

    engine = new Engine({
        b: 2
    })

    engine.solve(['==', ['get', 'a'], ['+', ['get', 'b'], 1]], 'my-tracked-constraints')
    console.log(engine.values) // {b: 2, a: 3}

    engine.solve({b: 5}) // change external value
    console.log(engine.values) // {b: 5, a: 6}

    engine.solve({b: null}) //remove external value
    console.log(engine.values) // {a: 0, b: -1}

    engine.remove('my-tracked-constraints')
    console.log(engine.values) // {}
