[PYTHON] JSON formatting

From http://stackoverflow.com/questions/352098/how-to-pretty-print-json-script.

From the command line, python -mjson.tool is easy.

$ echo '{"foo": "lorem", "bar": "ipsum"}' | python -mjson.tool

In JavaScript, you can add an indentation level to the third argument of JSON.stringify ().

JSON.stringify({ foo: "lorem", bar: "ipsum" }, null, 4);
