The SmartColumnLayout place's its target Group's children into a fixed set of columns determined by numColumns which defaults to 3.

Each child's width is changed so that all of the columns maintain the same width. Each child's height is retained, however, unless the child is less than minRowHeight.

This pattern means that the columns will be of differing heights. Whenever a new child is added to the end of the target Group's display list, it is added to the shortest column.

When a child is deleted, the children below it in its column are moved upward, the other columns are not affected.
