Everything we have, feature wise, is now documented in a first version
at least.
We shall keep this uptodate with what we are implementing, which also
helps figuring out a good api.
A note like that is now added to all files we generated, commented out
depending on the file type.
Quite neat, except that for filtering, I always have to use blocks.
Previously, they were in an extra, oddly named crate.
Now we just make it a part of our generated codebase.
That way, traits, and common code, shows up as part of the library.
Fair enough.
This also means that the types ar not reusable.
Maybe a mixed-mode can be used if that is desired.
Now a context is passed to utility functions, which contains the state
these may be interested in. This keeps it clean from global state.
With the lookup tables, it is possible to figure out relations between
types and document them accordingly.
