Add json output

[DeGraciaMathieu]

Hi,

Could we possibly add a JSON output format for the analysis results ?

This would enable us to interface with the tool. I often use small PHP scripts to retrieve and analyze PHPMetrics results.

Good idea. It's a good first step anyway for an external contribution. I'll see if I can document the subject enough, otherwise I'll do it.
