%description
Artificial Neural Networks Toolbox
- Only layered feedforward networks are supported *directly* at the 
  moment (for others use the "hooks" provided)
- Unlimited number of layers
- Unlimited number of neurons per each layer separately
- User defined activation function (defaults to logistic)
- User defined error function (defaults to SSE)
- Algorithms implemented (so far):
  * standard (vanilla) with or without bias, on-line or batch
  * momentum with or without bias, on-line or batch
  * SuperSAB with or without bias, on-line or batch
  * Conjugate gradients
  * Jacobian computation
  * Computation of result of multiplication between "vector" and Hessian
