Array2D - Enhance to include ability to create 2D array using either [col][row] or [row][col] subscripting.

[l-rettberg]

Brief Intro

The Array2D algorithm is based on using column then row, ie [col][row] when accessing cells. Not sure if that is the commonly used approach? I thought the most common was row, column, ie [row][col], but perhaps that's really up to the developer.

More Details

Suggest updating the algorithm to include a boolean flag that the caller can define whether the 2D array should be created as [col][row] or [row][col] for most flexibility.
