Separate generators from generatED files

@michaeldgraham according to `git blame` you wrote most of the "tck"
tests. I have a hard time what "tck" actually means. Could you explain?
Maybe: "Test Compatability Kit"?

I find the name confusing. Could we
* either use the unabbreviated name or
* use another more descriptive name?
