A Forest of Trees and Structured Adaptive Refinement (DMFOREST)

The DMFOREST subclass of DM encapsulates an octree mesh, with interfaces for both topology and geometry. It is capable of parallel structured adaptive mesh refinement and coarsening and parallel redistribution for load balancing. It is designed to interface with the PetscFE and PetscFV discretization objects, and converts smoothly to a DMPLEX.
