	Print the public fields and methods of the specified class (output similar 
	to the JDK javap command).
	<p/>
	If the argument is a string it is considered to be a class name.  If the
	argument is an object, the class of the object is used.  If the arg is a
	class, the class is used.  If the argument is a class identifier, the class
	identified by the class identifier will be used. e.g.  If the argument is
	the empty string an error will be printed.
