+Improved: A new dummy enumeration AD::NumberTypes::none has been added.
+It exists to represent number types that are scalar arithmetic types, 
+i.e those that hold no derivatives. They are implemented primarily to 
+facilitate the use of template  meta-programming techniques to switch 
+between different AD types. This covers the case when the user does not 
+want an AD type at all, but rather a primitive type.
