Created a directory to collect the workflow output data

[LanderOtto]

This commit implements the suggestion of #464
An output directory was added with the name of the workflow and for each output port of the workflow a dedicated directory.
Therefore, it is possible to use in multiple runs the same outdir and have organized directories for each run.
