Lacking documentation for the `public` directory
Tried to use HappyX today but I'm a bit confused. Basically I just wanted to try out a very simple SSG with some static HTML/CSS files and a route to catch the input from a form. I created my project using `hpx create --name test --kind SSG` and it created the project structure for me. I dropped some files into the `public` folder but the server doesn't seem to serve these files. Looked at the examples and the only one which appears to do this is the `nim-lang` one and it appears to serve them with the `public` prefix on, however trying that didn't make it serve my file either. So I'm not sure if I need to do something to make HappyX serve the files from the `public` directory or not, it doesn't log requests either so I don't really know what's going on..

This was tested with the latest tagged version of HappyX (which is the 1.0.0 release)
The project structure is simply the one created by `hpx create --name test --kind SSG` with an additional file added in the `src/public` folder.
The code is exactly what was generated. I looked at the nim-lang site example which has a public folder but couldn't see any special handling of it.
