/** \class ErrorBackPropagationLearningWithMomentum
* \brief The ErrorBackPropagationLearningWithMomentum is the base
* class for all the ErrorBackPropagationLearning strategies.
*
* ErrorBackPropagationLearning strategies include error back propagation,
* bp+momentum, conjugte gradient descent, and 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
