[Feature] - Add grid layout and staggered grid layout #54
Description
Columns and rows are find for a small number of its. But beyond that we need grids.
We should add a standard grid of rows and columns of equal size.
We should also add one or more variations of a staggered or dynamic grid. This is a grid where one item might take up 2 or 4 units, while other items just take up 1 unit. Think about a Scene for the Obsidian editor. The first golden appears in the Obsidian frame, and therefore takes up a lot of space. But then every editor after that is displayed without a frame, thereby taking up much less width. This is kind of like a magazine layout where some pieces are featured, but other pieces are placed in between.
