pruning code works
 test the usefulness of the input mask on a 50-D environment (the 5D environment repeated 10 times). Input mask allows final lower error, but not always faster learning in the beginning

control with 1 single FFN mapping all inputs sm to outputs s with 2 layers 100-100 nodes
2 layers. comparing 2 layers vs 1 layer, comparing all inputs vs expected input mask
 2 layers vs 1 layer, 5 hidden nodes vs 50 hidden nodes. + Evolution
