Description

This model demonstrates how to read more than one parameter from in single CSV
file. However, this cannot be done with CSVRead directly, since CSVRead returns
one single parameter. The data must be split later on.

This model is referenced in "Getting Started Example 4 - Reading more than one
parameter from a single input file" from the CSVRead Documentation.

* it is necessary to declare the dummy parameter dataPar at first
