Errors and problems on the 'Code examples' page.

Errors and problems found on the site http://bluebrain.github.io/RTNeuron-3.0/python/gallery.html

1.- DONE In 'Getting Started': Not clear what the 'snapshot' function does:
rtneuron.snapshot_to_notebook(rtneuron.engine.views[0])

2.- In 'Getting Started' 7th code block I get a bunch of output that is not clear to me:
````In [5]: rtneuron.display_circuit(blueconfig, 6523)
...: # This function doesn't directly accept a dictionary for the attributes, it has to be
...: # an AttributeMap instead.
...: rtneuron.display_synapses(
...: 6523, attributes=rtneuron.AttributeMap({'color': [1, 1, 0, 1], 'radius': 3}))
...: rtneuron.snapshot_to_notebook(rtneuron.engine.views[0])

So far I have addressed 1, 3, 4, 5, 6 and 9. All the others that have to do with the simulation/circuit config will take longer. I wish there was a public dataset I could use instead.

[alex4200]

@hernando Item 9 does not yet seem to work. I still get the same error..

[hernando]

True, I didn't fully resolve it because blue.test is still not defined. You should be able to load some other configuration, however, I forgot to update the deployment. I'll get back to you when you can test again, should be done in a couple of hours.

[hernando]

You can try again now

Hi, I still get the same error when I follow the instructions... Alex

Number 7 should now be resolved.

[hernando]

Sorry, it isn't. I what confused by a build recipe used in CI that contains the test data. The recipe used in deployment doesn't contain it.
