It resembles a directory struture. Every node contains either a tile or a child. The root node contains only a child. Thus a node may be thought of as either a container or a tile. The current organizations are either a 2 dimensional grid, or a sequence of tiles. For a grid, the root node contains one child, this child has siblings for each row in the grid, or each column in the grid, depending on what the user asked for. If the user asked for Row, Column then each sibling is a row container, that is each sibling has no tiles but has a child. The siblings of that child correspond to the columns, and each one has a tile pointer but no children. For a sequence, the root node contains one child. The child and all its siblings contain tiles. If the naming scheme is numeric, then its appropriate to ask for the sequence. If alphabetic, then its more appropriate to ask for an alphabetized list.
