NAME

       Analizo::Metric::DepthOfInheritanceTree - Depth of Inheritance Tree (DIT) metric

DESCRIPTION

       The metric calculation is based on the following article and calculates the longest path from a module to
       the class hierarchy root.

       Article: An empirical study of aspect-oriented metrics by Eduardo Kessler Piveta, Ana Moreira, Marcelo
       Soares Pimenta, Joao Araujo, Pedro Guerreiro and R. Tom Price.

       See the adaptation of the paragraph about Depth of Inheritance Tree in the article:

       Considering a function "s(x) : Module -> Module" that computes the super-class or super-aspect of a giver
       module, the value of DIT is given by:

         DIT(m) = DIT(s(m)) + 1, ifc m != rootClass
         DIT(m) = 0, otherwise.
