Detailed Description

Class for generation AMR boxes using a tiling algorithm.

This class provides a scalable method for grid generation where the grids are generated in a pre-set tile pattern. This work by decomposing the grid into a tiled pattern, and then flagging tiles rather than cells for refinement.
