Workflow to show Column Filter examples

This workflow is based on adult.csv data set and demonstrates column filter examples using manual selection with a Column Filter node or using a Reference Column Filter node. Exercises: 1. remove column "marital-status" 2. keep only column "marital-status" 3. keep only String columns using a Column Filter node and then only column "marital-status" using a reference table and a Reference Column Filter node
