demo: simplify helloworld example [WIP]
Created by: hjhsalo
- Simplify helloworld example
WIP:
- reana.yaml is just a quick mockup, to demonstrate how reana specification file could be used. For example, it contains a JSON string that should be presented as YAML list. Might fix this before merging, but given that there have been plans to change to python-based cli-script, implementing YAML in shellcode might not be worth it. (reanahub/reana/pull/20)
- Currently writes to output file. This might change to stdout.
