ES Proposal spec-compliant shim for AggregateError. Invoke its "shim" method to shim `AggregateError` 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://tc39.es/proposal-promise-any/#sec-aggregate-error-object-structure).

Most common usage:
```js
var assert = require('assert');
var AggregateError = require('es-aggregate-error');

var oneError = new RangeError('hi!');
var otherError = new EvalError('oops');
var error = new AggregateError([oneError, otherError], 'this is two kinds of errors');

assert.deepEqual(error.errors, [oneError, otherError]);
assert.equal(error.message, 'this is two kinds of errors');

AggregateError.shim(); // will be a no-op if not needed

assert.ok(new globalThis.AggregateError([]) instanceof AggregateError);
```

## Tests
Simply clone the repo, `npm install`, and run `npm test`
