Add a new function that decomposition a Box into BoxArray. The number of Boxes in the returned BoxArray matches the given nboxes argument, unless the domain is too small. We aim to decompose the domain into subdomains that are as cubic as possible, even if this results in Boxes with odd numbers of cells. Thus, this function is generally not suited for applications with multiple AMR levels or for multigrid solvers. However, it could be useful for single-level applications that prefer exactly one Box per process.
