Thanks for the honest reply. Fair enough, I could have "shown more effort", but I didn't want to write more words just to say "I tried but failed to understand pretty much all of it". It's not that I don't know anything about the subject, I just needed to understand what problem the OP was talking about to begin with, then I'd be able to hook it into my current knowledge. Also, by being pointed to a practical application it becomes much easier for me to understand the theory, hence the way I worded it. mywittyname's reply nails my intention and thought process, and IncRnd's reply perfectly answers my question, so I hope this thread amounted to a positive contribution after all.
