Simple request: plain output

I need a plain output layer, I could also implement it myself if you give some hint.

I want to do a time series forecasting and it took a while to realize I was misusing the softmax layer which is not what I need.

I don't need the GPU version, so:

I think I should implement a subclass of OutputLayerBase that relies on some CpuDnn.SOMETHINGFORWARD.. correct?
