standardized, reusable output formats (e.g json and png)

[danwos]

Providing more standardized output formats for diff, report and graph to support the development of tools on top of wily.

To embedded the wily results automatically (CI) in other tools/documents, a machine readable format would be great.

use cases

The graph output could be easily integrated into word-docs or wiki-pages, if png as output format is supported.

The report and diff output as json string/file would allow a CI to evaluate the results during build and maybe reject a commit because of too high complexity.

my motivation

I'm personally thinking of creating an extension for sphinx: sphinx-wily. To get the wily results easily into a documentation during build time. But I want to avoid parsing any kind of cli-output, if it is not using any standard (too risky that such an output gets changed over time).

I may find some time to dive into wily and provide a PR which implements at least a json output. But no guarantee for this.

So any thoughts or concerns regarding additional output formats?

BTW: Thanks for this great tool. Performing an analysis over the git history is really an awesome feature.
