Flow around a sphere with ADAPTIVE (dynamic) mesh refinement for the lbm_generated module.

In contrast to the (static) MeshRefinementExample, the block forest is re-partitioned during the simulation: blocks are refined where the velocity field shows strong gradients (the sphere and its developing wake) and coarsened again in calm regions. The refinement is performed via blockforest->refresh(), which migrates all block data (the PDF field, the macroscopic fields and the flag field) between the refinement levels and re-balances the load across processes.
