The method call returns the new workflow ID of the restored workflow.

A restored workflow has the status INITIATED and needs to be started using the start() method.

Workflows are stored, e.g., by using the store method.

Specified by:: restore in interface GWES

Parameters:: workflowID - The old workflow ID of the stored workflow.; userID - The user ID.
Returns:: The new workflow ID of the restored workflow.
