Split of a API module

[jensim]

I would like to see a an API-module split from the logic part of this. For the code I am currently working on, I have 0 need for creating schemas in my running code. But I must have the annotations provided by this lib in my data-classes, and am therefore forced to ship this entire lib, not just the annotations, with my dependencies. (I'm generating schema in the test-phase and doing a compare with a static schema file that i have stored in my resources in order to detect if my static schema is up to date with my kotlin code)
