Enhance UserProfileService with ability to import a CSV dataFile

I would like to be able to initialize the default set of UserProfiles that accompany the default set of users that can be initialized via a SQLDirectoryFactory CSV dataFile. This could be accomplished by adding a "dataFile" attribute to the UserProfileService descriptor that references a CSV file from which UserProfiles are populated. I suspect some of the logic included in the new Nuxeo CSV module could be leveraged to implement such a feature.
