Add a (not yet working) brian2 version of the barrelcortex example
Use scalar variables for the stimulus (example is still work-in-progress).
Still trying to make the example work (stimuli seem to be ok now)
Slightly more verbose debug output for created synapses.
New version of the barrelcortex example: now working, but standalone gives weird results...
Sort objects into a reproducible order for identical when/order attributes (using their name).
New version of barrelcortex example that does not rely on subgroups for connections and seems to be working fine with standalone.
Use subgroups in the barrelcortex example, now that this is working with standalone
