Sort the output (for now just the classes and instance members).

Maybe describe what kind of sorting this implies? Here you are assuming that the
ids are increasing within a source file?

I added a comment. We don't rely on the sorting and it is not crucial that the
ids increase with the source file. But yes. that's the intention.

+      return class2.id - class1.id;
+    });

       generateClass(element, buffer);
