Would be useful to visualize the changes of weights and charges/states over training, as well as the spike raster, in something like Matplotlib

• Visualization of synaptic weights over time
• Visualization of neuron charge states over time
• Visualization of spike raster, as a proper plot (not just ascii art)

Describe the solution you'd like
A clear and concise description of what you want to happen.

Have an easy way to visualize the weights and states changing through time

As well as an easy way to plot the spike raster

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Have functions that turn the model into things that can be plugged into matplotlib, rather than just doing the plotting as part of the function
