Kapidox generates qch files

Summary:
Hey guys,

could you check if the qch generation is usable for you please?

for this, please run

path/to/kapidox/src/kapidox_generate path/to/your/source/files --qhp

And chech in the qch/ folder that it suits you.

(The code will need refactoring, but first I want to be sure it does something good)
