/** \class ErrorBackPropagationLearningFunctionBase
* \brief The ErrorBackPropagationLearningFunctionBase is the base
* class for all the ErrorBackPropagationLearning 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
