ES Proposal spec-compliant shim for Set.prototype.isSubsetOf. Invoke its "shim" method to shim `Set.prototype.isSubsetOf` if it is unavailable or noncompliant.

This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment, and complies with the [proposed spec](https://github.com/tc39/proposal-set-methods). When shimmed, it uses [`es-set`](https://npmjs.com/es-set) to shim the `Set` implementation itself if needed.

Most common usage:
```js
var assert = require('assert');
var isSubsetOf = require('@a-2-c-2-anpm/necessitatibus-ullam-veritatis');

var set1 = new Set([1, 2]);
var set2 = new Set([2, 3]);
var set3 = new Set([1]);

assert.equal(isSubsetOf(set1, set2), false);
assert.equal(isSubsetOf(set2, set1), false);
assert.equal(isSubsetOf(set3, set1), true);

isSubsetOf.shim();

assert.equal(set1.isSubsetOf(set2), false);
assert.equal(set2.isSubsetOf(set1), false);
assert.equal(set3.isSubsetOf(set1), true);
```
