urbanczik_synapse - Synapse type for a plastic synapse after Urbanczik and Senn.
urbanczik_synapse is a connector to create Urbanczik synapses as defined in [1] that can connect suitable
multicompartment models. In contrast to usual STDP, the change of the synaptic weight does not only depend on the pre-
and postsynaptic spike timing but also on the postsynaptic dendritic potential.
Urbanczik synapses require archiving of continuous quantities. Therefore they can only be connected to neuron models
that are capable of doing this archiving. So far, the only compatible model is pp_cond_exp_mc_urbanczik.

All other parameters are stored in in the neuron models that are compatible with the Urbanczik synapse.

So far the implementation of the urbanczik_synapse only supports two-compartment neurons.
