There already is a json parser example in

I think it would be good to move it to the boost::spirit repository and
to the release branch. It may be also a good idea to use this parser in
the boost::property_tree instead of the current one.

The structure used in the spirit/example/qi/json/ looks reasonable: the
json object is represented as a map<string, value> and the value is
represented as a boost::variant (with some wrapper around it).

I don't like the boost::property_tree approach because it loses all the
type information for the values.
