The CompetitiveNeuron class provides neuron behaviour specific for
competitive neurons which are used in competitive layers, and networks with
competitive learning.
Creates full connectivity within layer - each neuron with all other
within the same layer with the specified weight and delay values for all
conections.
The SummingFunction is abstract base class for components of neuron's
InputFunction which performs some summing operation on weighted input vector
and returns scalar
The WeightsFunction is abstract base class for components of neuron's
InputFunction which perform some operation on neuron input vector and weight
vector.
