When i assign object attributes:
import Rhino
result, obj_ref = Rhino.Input.RhinoGet.GetOneObject("Select object", False, Rhino.DocObjects.ObjectType.AnyObject)
obj_ref.Object().Attributes.SetUserString("my_key1", "0"); #obj_ref.Object().Attributes or obj_ref.Object().Geometry
obj_ref.Object().Attributes.SetUserString("my_key2", "1");
next time I select an object of rhino how can I iterate through all keys and values?
In which property they are stored?
