ParamsTree

This is a little helper to turn strings like:

"default(id,user(group(division(name)),name)),post(id,title),comment(id,author,text(title,body))"

to:

{
  "default" => {
    "id" => {},
    "user" => {
      "group" => {
        "division" => {
          "name" => {}
        },
        "name" => {}
      },
      "post" => {
        "id" => {},
        "title" => {}
      },
      "comment" => {
        "id" => {},
        "author" => {},
        "text" => {
          "title" => {},
          "body" => {}
        }
      }
    }
  }
}
