metric
The metric calculation is based on the following article and calculates the
class connectivity.

See the adaptation of the paragraph about Afferent Connections per Class in the
article:
Measures the connectivity of a class. If a class "Ci" access a method
or attribute of a class "Cj", consider "Ci" a client of
the supplier class "Cj", denoting "Ci => Cj". Consider
the follow function:
client(Ci, Cj) = 1, if (Ci => Cj) and (Ci != Cj)
client(Ci, Cj) = 0, otherwise.
So "ACC(Cj) = (sum(client(Ci, Cj)), i = 1 to N)", where "N"
is the total number of system classes. If the value of this metric is large, a
change in the class has substantially more side effects, making maintenance
more difficult.
