Simple mongoose model mocks for jest unit tests

### Sample usage

```javascript

//users.controller.test.js

const MockModel = require("jest-mongoose-mock");

jest.mock("./user.model", () => new MockModel());

const Users = require("./user.model");

const usersController = require("./users.controller");

describe("registerUser", () => {

    let req, res;

    beforeEach(() => {

        jest.clearAllMocks();  //reset mock calls

        req = { body: {} };

        res = { json: jest.fn() };

    })

    it("Calls create & exec methods on User model", () => {

        usersController.register(req, res);

        expect(Users.create.mock.calls.length).toBe(1);

        expect(Users.exec.mock.calls.length).toBe(1);

    });

});

```

```javascript

//users.controller.js

const Users = require("../models/User.model");

exports.register = (req, res) => {

    const user = req.body;

    Users.create(user).exec((e, user) => {

        if (e) {

            return res.send(e);

        }

        res.json(user);

    });

};

```

```javascript

//user.model.js

const mongoose = require("mongoose");

const schema = mongoose.Schema({

    name: {

        type: String,

        required: true

    },

});

const Users = mongoose.model("User", schema, "users");

```
