An ES2017 spec-compliant Object.values shim. Invoke its "shim" method to shim Object.values if it is unavailable or noncompliant.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec.

Most common usage:
```js
var assert = require('assert');
var values = require('object.values');

var obj = { a: 1, b: 2, c: 3 };
var expected = [1, 2, 3];

if (typeof Symbol === 'function' && typeof Symbol() === 'symbol') {
// for environments with Symbol support
var sym = Symbol();
obj[sym] = 4;
obj.d = sym;
expected.push(sym);
}

assert.deepEqual(values(obj), expected);

if (!Object.values) {
values.shim();
}

assert.deepEqual(Object.values(obj), expected);
```
