KORE milestone 1

**please review**

 - unit-tested convertors from KORE to KIL and back
 - significant changes and simplifications to KORE data structures. They are smaller and more powerful now

Ok, Radu. Regarding the original issue, I've reverted the entire fire to its master version, and only added my change. My name is still on four more lines then it should be but all of them are unimportant (comments and an empty constructor).
