Bad

`codec.py` is imported by eight modules and imports two, so `I` is `0.2`. It imports `cli.py`,
which imports six modules and is imported by none, so `I` is `1.0`. Every edit to the command
line can now reach the codec, and through it the eight modules that depend on the codec. This
returns `1`.


Good

cli.py imports codec.py. The arrow runs from the volatile module to the settled one, so a change to the command line reaches nothing and a change to the codec is a decision somebody made deliberately. This returns 0.
