How to correctly use nim doc when a project has unimported modules

[haxscramper]

But once there is a separate stage design like this it is possible to twist and 
turn it as needed, like integrating test runs into the nim doc (virtually no

directories for more docs, operating on documentation in terms of nested 
directories, subprojects, import graphs, queries like "who returns X" and so on.
