def ==(par)
  if par.kind_of?(Integer) or par.nil? or par.kind_of?(Float) then
    super(par.to_s())
  else
    super(par)
  end
end

#json(*keys) ⇒ Object

In case the string is a json it will return the keys specified. the keys need to be provided as symbols input: keys: 1 value with key or an array of keys In case the key supplied doesn't exist in the hash then it will be returned nil for that one output: if keys given: a hash of (keys, values) or the value, if the key is found more than once in the json string, then it will be return a hash op arrays if no keys given, an empty hash
