The layout objects are a collection of "feature" classes that define how items in a 2d grid are ordered.
TERMINOLOGY: A "feature" or "method" class is used to define features for a template class and are not meant to be used directly.
## RowMajorLayout
The first item is in the upper left. Then the numbering within the layout moves through the row, then continues on the left of the next row.
There are three related objects with the same layout, but they are rotated 90, 180, and 270 degrees clockwise.

```
no rotation rotated 90 rotated 180 rotated 270
00 01 02 03 12 08 04 00 15 14 13 12 03 07 11 15
04 05 06 07 13 09 05 01 11 10 09 08 02 06 10 14
08 09 10 11 14 10 06 02 07 06 05 04 01 05 09 13
12 13 14 15 15 11 07 03 03 02 01 00 00 04 08 12
```
## RowMajorAlternatingLayout
The first item is in the upper left. Then the number within the layout moves through the row, then continues on the right of the next row moving toward the left; repeating this alternating pattern through the layout.
There are three related objects with the same layout, but they are rotated 90, 180, and 270 degrees clockwise.

```
## ColumnMajorLayout
The first item in in the upper left. Then the number within the layout moves down the column, then continues on the top of the next column moving downward again.
There are three related objects with the same layout, but they are rotated 90, 180, and 270 degrees clockwise.
