Set the weights assigned to each of the cells (see <A HREF="../DM/DMForestGetCellChart.html#DMForestGetCellChart">DMForestGetCellChart</A>()) of the current process: weights are used to determine parallel partitioning. Partitions will be created so that each process's ratio of weight to capacity (see <A HREF="../DM/DMForestSetWeightCapacity.html#DMForestSetWeightCapacity">DMForestSetWeightCapacity</A>()) is roughly equal. If NULL, each cell receives a weight of 1.
