        Method for a UI to delete a bean.

        The UI should first request a "CanDelete", this will return a list of locations (and descriptions) where the bean is in use via throwing a VetoException, then if that comes back clear, or the user agrees with the actions, then a "DoDelete" can be called which inform the listeners to delete the bean, then it will be deregistered and disposed of.

        If a property name of "DoNotDelete" is thrown back in the VetoException then the delete process should be aborted.
