* \brief The LearningFunctionBase is the base class for all the learning strategies.
*
* These include error back propagation, bp+momentum, conjugte gradient descent, quick prop.
*
* This class specifies how the errors are backpropagated for a layer. They take a LayerBase
* object as input and compute the input for the layers input weightset.
