Standard Groups
===============

Some standard types of :class:`NeuronGroup` have already been defined.
:class:`PoissonGroup` and :class:`PoissonInput` to generate spikes with Poisson 
statistics, :class:`PulsePacket` to generate pulse packets with specified 
parameters, and :class:`SpikeGeneratorGroup` to generate spikes which fire at 
prespecified times.
