This started out as an introductory chapter to a book that never materialised - I leave it to my fellow wikipedians to decide if it is sufficiently NPOV
A longer version is available on my personal website - clasqm
Not to give any deeper comment for now: it needs to be rendered from a third person POV (i.e., get rid of the "I" comments; who are you, and why should we care what you, the author of an unsigned article, think? ;-) ). The article definitely deserves more in-depth attention, of course! Thanks for the contribution! --
