es-set-tostringtag

A helper to optimistically set Symbol.toStringTag, when possible.

Most common usage:
```js
var assert = require('assert');
var setToStringTag = require('es-set-tostringtag');

var obj = {};

assert.equal(Object.prototype.toString.call(obj), '[object Object]');

setToStringTag(obj, 'tagged!');

assert.equal(Object.prototype.toString.call(obj), '[object tagged!]');
```
