added comments and structure in main program
done parsing training data, now need to implement backbrop_learn
backprop_learn wasnt returning anything... now ready to implement it.
added structure to backprop_learn, need to check whether forward propagation works
backprop_learn doesnt crash, but needs debugging
fixed some bugs in training, need to look at adjustment of weights step
fixed a bug with adjusting weights, need to debug training more.
about to branch and try training algorithm with for loops
restructured neural net class, moved data file parsing into a separate method.
almost done with testing, need to check micro numbers
done with testing, need to fix backpropagation
