Abstract base class for all neuron groups.
This class constitutes the abstract forefather of all neuron groups in the simulator. It serves as target for Connection objects and is directly derived from SpikingGroup. It directly allocated the memory for mem (membrane potential) and the synaptic conductantes (g_ampa, g_gaba, g_nmda) as well as a vector to store the thresholds. The detailed implementation of the evolve() function depends on the children of NeuronGroup.
