What is the best way to achieve modular separation or HMVC in CI3?

Wiredesignz' HMVC works fine with CI3, as long as you use the CI3 version (which is what you've linked), and you extend the MX_Controller in your base controller (or in all of your controllers if you don't have a base controller). The controllers created in any modules would also have to extend MX_Controller or another controller which extends MX_Controller.

By default, it routes http://localhost/contacts to /application/modules/contacts/controllers/Contacts or /application/controllers/Contacts (it will search the paths in that order). If you wanted it to only route to the modules directory when you used http://localhost/modules, you'd have to modify the MX_Router.
