stdp_synapse_hom - Synapse type for spike-timing dependent
plasticity using homogeneous parameters.
multiplicative STDP [2] mu_plus = mu_minus = 1.0
additive STDP [3] mu_plus = mu_minus = 0.0
Guetig STDP [1] mu_plus = mu_minus = [0.0,1.0]
van Rossum STDP [4] mu_plus = 0.0 mu_minus = 1.0
stdp_synapse_hom is a connector to create synapses with spike time
dependent plasticity (as defined in [1]). Here the weight dependence
exponent can be set separately for potentiation and depression.
Parameters controlling plasticity are identical for all synapses of the
model, reducing the memory required per synapse considerably.

tau_plus ms Time constant of STDP window, potentiation
(tau_minus defined in post-synaptic neuron)
lambda real Step size
alpha real Asymmetry parameter (scales depressing increments as
alpha*lambda)
mu_plus real Weight dependence exponent, potentiation
mu_minus real Weight dependence exponent, depression
Wmax real Maximum allowed weight

The parameters are common to all synapses of the model and must be set using
SetDefaults on the synapse model.
