"""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
