... refactored scraping of cases
(Sorry, missing some of the discussion, github's being weird, so I'm hope I'm not repeating something: 
I mean - if you just want one node, you migth as well do ```courtLine[0].textContent``` no need to run ZU.xpathText.
If you do want multiple nodes (which seems to be the case), ZU.xpathText forces the comma as the delimiter, so only use that if that's what you want. Otherwise, run through all nodes with a loop, push text content to an array and ```.concat()``` with whatever delimiter you prefer.
