Create skeleton admin menu for a Users object

This should have basic resource routes and controllers. Create controller using `php artisan make:controller --resource` to have all the typical controller resource handling generated for you.

- [ ] Controller
- [ ] Route (use named routes)
- [ ] Views (create the most basic views, literally just spit out the required fields or lists and that's it. We'll stylise these in the future)

Use `php artisan make:controller --resource` to generate a Users controller. Define a resource route in `routes/web.php` with a name. Create basic Blade view files (index, create, edit, show) in `resources/views/users/` that output the required fields. Verify the routes work by visiting `/users`.
