Input ports
...........

    **data**
        | Type: table
        | Description: data

Output ports
............

    **result**
        | Type: table
        | Description: Table with results
    **clusters**
        | Type: [table]
        | Description: List of columns in each cluster
        | Optional number of ports: 0--1 (default: 0)
        



Configuration
.............

    **Create cluster column** (clust_col)
        Creates an additional column first in the data showing cluster ID that each row belongs to
    **Clusters** (clusters)
        Number of clusters to look for
    **Create name column** (name)
        Creates an additional column first in the data showing the original column name for each corresponding row
    **Sub clustering** (sub_clustering)
        Performs one level of additional clustering to order data within a cluster
