Tiling Quad

Substitution tiling for square tiles.

quadChild :: Quadrant -> Quad -> Quad

The child tile at a given quadrant.

quadParent :: Quad -> Maybe (Quadrant, Quad)

The parent with quadrant information for the tile. Satisfies:

 quadParent (quadChild c q) == Just (c, q)

quadPath :: Quad -> [Quadrant]

The path from this tile to the root. Satisfies:

 foldr quadChild root (quadPath q) == q

quadFile :: Quad -> Maybe ([FilePath], FilePath)

Suggested file system location for data pertaining to a Quad.
