Set up data flows

[loleg]

We need to set up a simple process to ensure reproducible results. I would use DataFlows, but Snakemake, Renku, Nextflow and Workbench have been suggested by our team as well. I think we should at least stay true to DataFlows philosophy:

• use it for data that easily fits on your hard drive
• all data produced by these flows is easily reusable by others
• not a heavy-weight framework
• machine and human readable interface
