DMForestSetWeightCapacity

During the pre-setup phase, set the capacity of the current process when repartitioning a pre-adaptation forest (see DMForestGetAdaptivityForest()). After partitioning, the ratio of the weight of each process's cells to the process's capacity will be roughly equal for all processes. A capacity of 0 indicates that the current process should not have any cells after repartitioning.
