[Zope-CMF] CMFSetup and workflows

[Anahide Tchertchian]

Hi,

I'd like to make 3 main changes to the way CMFSetup handles workflow
export/import:

- turn import methods in CMFSetup/workflow.py into configurator class
methods so that they're easier to override when subclassing
(_extract*Nodes and _initDCWorkflow* methods)

- get rid of DCWorkflow specifics, and use the workflow factory and
API methods to import a workflow (no need to import
DCWorkflowDefinition, State, Transition classes anymore, for instance)

- do not list workflows that are not supported when exporting (not
supported workflows are listed but not exported at the moment)

Any opinions/suggestions?

Thanks,
anahide.
