+using a method proposed by Chidamber and Kemerer in 1994. The idea
 behind measuring a class's cohesion is that most functions in well-designed
 classes will access the same fields. Types that exhibit a lack of cohesion
 are often trying to take on multiple responsibilities, and should be split
 into several smaller classes.

+Various measures of lack of cohesion have been proposed: while the basic
 intuition is simple, the precise way to measure this property has been the
 subject of intense debate. Rather than getting involved in this debate,
 more than one such lack of cohesion measure is provided for comparison purposes.
