Feature Request: Cohesion and Coupling metrics

[AlexandruBurlacu]

Hi,

I was wondering whenever adding a subset of Chidamber and Kemerer programming complexity metrics would be of interest to you and in the scope of radon tool?

While using radon I found it more effective in finding methods/functions that are complex, rather than tightly coupled, so I believe having a couple of metrics to estimate coupling and cohesion would be nice.

Some of the more popular metrics are LCOM and RFC, which are focused on estimating program coupling and cohesion. Here is a short Wikipedia description of these metrics, and here's the original paper.

P.S. I really like your project and use it sometimes, both for personal projects and work. It really helps when figuring out what refactoring to do next.

Thanks Alexandru, much appreciated! Right now I don't have time on hand to implement new metrics, but if you open a new PR with some features and the corresponding test cases I'll be happy to review it!
