docker's metrics

goviz has a function which outputs the metrics (instability) of go project.

goviz -i github.com/dotcloud/docker/docker -m

Instability is a value of 0 to 1. It suggests that it is such an unstable module that this value is high. It becomes easy to distinguish whether it is a module nearer to application layer, and whether it is a module near a common library.
