Bias not being applied?

[dcuny]

In line 231 of NeuralLua.lua, the comment says this line is applying bias:

  -- aplying BIAS
  b = #neural.bias
  i = 1 
  k = #neural.weights
  while i <= #neural.weights do
    neural.weights[i] = matrix.sum(neural.weights[i],deltas[k])
    i = i+1
    k = k-1
  end

However, it appears to be a cut and paste of the line above, without changing neural.weights[i] to neural.bias[i].

It's not clear how you're applying bias, but it's likely that it can be applied in the same loop that the weights are being applied, instead of requiring another loop.
