+"""Class browser.
+
+XXX TO DO:
+
+- reparse when source changed (maybe just a button would be OK?)
+ (or recheck on window popup)
+- add popup menu with more options (e.g. doc strings, base classes, imports)
+- show function argument list? (have to do pattern matching on source)
+- should the classes and methods lists also be in the module's menu bar?
+- add base classes to class browser tree
