Does lots of refactoring.

-> Removes most commented code (You can always check trunk)
-> Adds a lot of JavaDoc with NOTEs if there has been a bold design choice
-> Adds @Override annotations whenever a method gets overridden or implemented from an interface
-> Makes a lot of methods and classes private or package-local, because the scope can never be to small
-> Replaces some implementations with lambdas
-> Changes deprecated implementations to newer ones
