These are open-ended questions that can't really be answered in forum posts; it would take way too much time for anyone to do so. But they can be answered by going through the source code (as I have done in the past to learn how the library works). I suggest you start with that, and if you have a specific question you come back here for help.
And, again, you need to fix your display name now.

There is no detailed discussion of its inner workings anywhere to my knowledge, and I'm likely to know as I'm the current project lead. The source code is available on SourceForge.
