committed already scratch that. Thanks for fixing the style).

> Implement a gradient machine (aka 'neural network) that can be used for
> classification or auto-encoding.
> It will just have an input layer, identity, sigmoid or tanh hidden layer and
> an output layer.
> Training done by stochastic gradient descent (possibly mini-batch later).
> Sparsity will be optionally enforced by tweaking the bias in the hidden unit.
> For now it will go in classifier/sgd and the auto-encoder will wrap it in the
> filter unit later on.
