 """ 
     Todo:
+        [] implement connection strength based on right or wrong answer
+        [] during 0 training if 1-9 output neuron fires, adjust weight only those neurons
+        [] implement dormant connection 
         [] using RL to control learning signal
         [] consider using Dates.now() instead of timestamp because time_stamp may overflow
         [*1] training should include adjusting α, neuron membrane potential decay factor
