In the meantime I found this code: https://gist.github.com/robotlolita/ccecb9b6781ba085d142040a943e1a96
It does what I want to do. As a follow up question: Does anyone know of a tool that allows users to visually compose flows, similar to the way it is done in Azure ML Studio (http://blogs.technet.com/resized-image.ashx/__size/550x0/__key/communityserver-blogs-components-weblogfiles/00-00-01-02-52/Azure-ML-Operationalization.png)?
