withParams and artifacts passing

[8th-block]

What is the best way to pass artifacts in the loop workflow?

          /--> parseFile1 ---> vectorizeFile1 --> ...
getFiles -
          \--> parseFile2 ---> vectorizeFile2 --> ...

I have no problem passing parameters in but when it comes to artifacts that does not work. The docs are sadly and I could not locate good samples for my use-case.
