v0.2.0

Release changes:

This release adds two models to the library:

The AdEx [1] and TripodNeuron [2] models. These models implement conductance-based synapses.

We also added models for Spiking Synapses with sparse matrices. Several plasticity mechanisms are implemented for the spiking synapses in AdEx and Tripod. Two forms of excitatory plasticity (STDP[3] and vSTDP [4]) and two forms of homeostatic inhibitory plasticity (iSTDP [5]), one that regulates the firing rate and one that regulates the membrane potential of the neuron.

The release also presents a stronger type structure, which benefits performance. I also improved the plot functions, adding new functionalities to raster and vecplot.

To Do:

• Module Organization: We have to move the plots to SNNPlots entirely.

• Performance: Implement parallelization for populations and synapses. Possibly using Dagger.jl
