NAME

       Analizo::GlobalMetric::ChangeCost - Change Cost global metric

DESCRIPTION

       The metric calculation is based on the following article and calculates the degree to which a change to
       any file causes a (potential) change to other files in the system.

       Article: Exploring the Structure of Complex Software Designs: An Empirical Study of Open Source and
       Proprietary Code by Alan MacCormack, John Rusnak and Carliss Baldwin.

       See the paragraph about Change Cost in the article:

       "... characterize the structure of a design is by measuring the degree of 'coupling' it exhibits, as
       captured by the degree to which a change to any single element causes a (potential) change to other
       elements in the system, either directly or indirectly (i.e., through a chain of dependencies that exist
       across elements).

       ... measures the percentage of elements affected, on average, when a change is made to one element in the
       system."
