Reading 3-dimensional arrays

Description

This example shows how to read a 3-dimensional array from an excel file (threedimarr.mos) and from a generic spreadsheet (threedimarr5.mos). Model versions (2) and (4) show the same example for databases, and model version (6) works with data in CSV format.
