     Todo:
         [*3] no "start learning" use reset learning and "inference", "learning" mode instead
-        [6] add time-based learning method. Also implement "thinking period"
-        [7] verify that model can complete learning cycle with no error
-        [4] synaptic connection strength concept
-        [5] neuroplasticity() i.e. change connection
+        [4] output neuron connect to multiple compute neuron

         [] using RL to control learning signal
         [] consider using Dates.now() instead of timestamp because time_stamp may overflow
         [] training should include adjusting α, neuron membrane potential decay factor
