This node populates a new column (appended to the input DataTable)
by executing the specified JPython function once per row in the
input DataTable. The values for each column in the input row
may be accessed via the
val("column name") (returning float,
int or string) or the
valplain("column name") (returning
the concrete cell object) JPython function. For example, a simple
JPython function to sum the values in 2 input columns might be:
val("col1") + val("col2")
Currently employs jython v2.2.1.
