Upon consideration, there are two options that should be considered.

1) Show each column as a port, as is currently done in the default, but output a
single ARRAY from each port where the length of the array is the number of rows
in the column. Some arrays would be doubles, some integers, and some strings,
depending on the content of the column. The number of rows would be implicit in
the vector lenght. (call this "ColumnVector" output?)

2) Optionally, have a single record port where named column arrays are the items
in the record (ie col name is the name of record item, with all columns
included).  This might be called a "Column-based Record" view and represents an
entire data table with a single record token.
