KARMA 2: GE parameter groups in plain English

This article has been chopped up into smaller, more modular articles and integrated into the KARMA 2: Tutorial - Mastering Level 3 ("KARMA Designer") KARMA Usage article.

This article is being kept around for a few more weeks because it was listed as new material in the most recent Karma-Lab newsletter and I want people who found this article through the newsletter to be aware of the new starting point for all this information. Eventually this article will be removed from the wiki.
