extend.Object: Extends another class

Description

Simply speaking this method "extends another class". What is actually happening is that it creates an instance of class name ...className, by taking another Object instance and add ...className to the class list and also add all the named values in ... as fields to the new instance. The method should be used by the constructor of a class and nowhere else.

Usage

## S3 method for class 'Object}(this, ...className, ...)':
extendundefined

 ...className{The name of new class.}
   ...{Named values representing the fields of the new instance.}

 Returns an Object of class className.

 
The reason for the strange name of argument "...className" is that
   if one tries to set a field with a name that is a prefix of the name of
   this arguments and one at the same time does not specify the name of this
   argument one would run into strange errors. For instance, try
   extend(Object(), "MyClass", ...c=0).
