Calltree¶
This module can be used to determine the calltree of a program. This can be helpful in understanding which functions calls which other function.
A callgraph is a graph of functions which call eachother.

Calculate the cyclomatic complexity.
Cyclomatic complexity is defined as:
C = E  N + 2 * P
Where: E = number of edges N = number of nodes P = number of connected components.
For functions and procedures P = 1.
So the formula for a single subroutine is:
C = E  N + 2
