fchurn v1.2.1

FChurn

File churn is a great way to see that a part of your application might be modified too often. This can indicate issues like a "god module/class" or logical pieces are too tightly coupled, making the software harder to change over time.

FChurn (File Churn) helps get a quick read on which files are seeing the most development and which are being created and then left alone.
