/**
	Return a new object that is a child of the specified object.
	<strong>
	Note: this command will likely change along with a better inheritance 
	mechanism for bsh in a future release.</strong>
	<p>

	extend() is like the object() command, which
	creates a new bsh scripted object, except that the namespace of
	the new object is a child of the parent object. 
	<p>

	For example:
	<p>

    <pre>
    foo=object();
    bar=extend(foo);

    is equivalent to:
      
    foo() { 
        bar() {
            return this; 
        }
    }

    foo=foo();
    bar=foo.bar();

    and also:
     
    oo=object();
    ar=object();
    ar.namespace.bind( foo.namespace );
    </pre>
	<p>

	The last example above is exactly what the extend() command does.
	In each case the bar object inherits variables from foo in the usual way.
