Geez, interesting but did you really think someone who calls himself a 
relative beginner that stated he needed help understanding class 
invariants could learn about them by reading this?  You almost need to 
know all about class invariants *first* in order to understand this 
Wikipedia article.  Around the time I would start to sort things out I'd 
get another obscure set of factoids and jargon thrown at me that would 
create a new set of uncertainty and eventually I spiraled down the 
rabbit hole of confusion scratching my head and saying WTF!  :-)  I'm 
sure with a few Google searches I may come up with some other stuff to 
read and perhaps with all of them it will start to become clear.  Thanks 
for at least taking the time to try and get me on the correct path.
