Make assertions about event emitters.

```js

const chai = require("chai");

chai.use(require("chai-events"));

const should = chai.should();

const EventEmitter = require("events");

describe("Event Emitting", function() {

  let emitter = null;

  beforeEach(function() {

    emitter = new EventEmitter();

  });

  it("should get emitted events", function() {

    let p = emitter.should.emit("get");

    setTimeout(function() {

      emitter.emit("get");

    }, 200);

    return p;

  });

  it("should handle non-emitted events", function() {

    emitter.should.not.emit("missing");

  });

  it("can be configured", function() {

    emitter.should.not.emit("another missing", {

      timeout: 50, // in milliseconds

    });

  });

});

```
