CodeIgniter4 User Guide

I have fixed the web-accessible CodeIgniter4 User Guide. It now pulls in CSS properly, so it is readable, and it pulls in Javascript, so it is searchable too.

This is for the "develop" branch, which means it is an "in progress" user guide, and its contents will change. I will update it periodically, as needed, and eventually move to an automated build & deployment after successful merges.

Thank you jlp!

But there is an example has missing "return".

It is in the follow page:
http://pneskin2.nekoget.com/codeigniter/...your-model

The method named "getNews" in "NewsModel" should have a return in the "if area" so that can return all rows from news table.

Thank you for reading this.
