1st, NNFlex works very well, specially because we can set the number of layers, nodes and extra configurations for each layer, what make possible to use NNFlex in many different problems.

I have rewrited your modules to fix some load and save (dump_state/load_state). Now I'm able to serialize the NN and load it with 100% of the previous state. Also the code is faster. Then I have added a new interface where is very easy to learn a set and get the output with the same values of the inputs.

I will send the code to you in sime days.
