+Subject: Updated codegen to work with python3.
+
+Most changes were just replacing usage of "has_key" with "in".
+Also updated the sorting function which was simplified and
+changed to a "key" function instead of "cmp" (which is no longer
+supported in python3. Verified everything builds with
+python 2.7 and 3.
