numRows which defaults to 3.
Each child's height is changed so that all of the rows maintain the same height. Each
child's width is retained, however, unless the child is less than minColumnWidth.
This pattern means that the rows will be of differing width. Whenever a new child is added to the end of the target Group's display list, it is added to the shortest row.
When a child is deleted, the children to its right are moved to the left, the other rows are not affected.
