Complexity
Written by Loren Segal in 2009
SYNOPSIS
Calculates the McCabe cyclomatic complexity index of the methods in your Ruby code.
The calculation is a basic NUMBER_OF_BRANCHES + 1 calculation which can be used
this calculation to approximate the minimum number of test cases for each of
your methods (complexity should equal number of test cases). You can also use
this value to find overly complex method and refactor them into simpler ones.
