+ Handle a class definition.
+
+ In order to translate python semantics reasonably well, the following
+ structure is used:
+
+ A special object is created for the class, which inherits attributes
+ from the superclass, or Object if there's no superclass. This is the
+ class object; the object which you refer to when specifying the
+ class by name. Static, class, and unbound methods are copied
+ from the superclass object.
+
+ A special constructor function is created with the same name as the
+ class, which is used to create instances of that class.
+
+ A javascript class (e.g. a function with a prototype attribute) is
+ created which is the javascript class of created instances, and
+ which inherits attributes from the class object. Bound methods are
+ copied from the superclass into this class rather than inherited,
+ because the class object contains unbound, class, and static methods
+ that we don't necessarily want to inherit.
+
+ The type of a method can now be determined by inspecting its
+ static_method, unbound_method, class_method, or instance_method
+ attribute; only one of these should be true.
+
+ Much of this work is done in pyjs_extend, is pyjslib.py
