Adding formatter to display the output

[skuppa]

Can we provide pluggable formatter and provide out of the box formatter such as xml, json to parse and display readable format to the user.

# without formatter
http://host:port > get persons
{[person {..}, person {..} ] }

# with formatter
http://host:port > set formatter json
http://host:port > get persons
{
  [
    person {..},
    person {..}
  ] 
}
