[matchings]

Updates to account for most recent version of AllenSDK which includes multiple stimulus blocks for each recording session. More info can be found under "data file changelog" here: https://allensdk.readthedocs.io/en/latest/visual_behavior_optical_physiology.html

Also a few additional references was added to the documentation in the markdown file for the Neurons page

@iamzoltan do you know what this failed check means? We need this update as soon as possible so the Allen Institute projects can run.

@iamzoltan Let me know if there is anything i can do to help troubleshoot the checks failing, or anything else to test and validate the changes to the notebooks that were part of this PR. I know its cutting it close to the start of the course, so I will be available most of today (July 7) to help.

@marius10p and @matchings yes this is cutting it very close to the course. Rushing like this is how things break. The process to make changes is as follows:

• Make your changes in a forked repo
• Create a PR to a staging branch
• We review the changes
• We then create a PR internally from the staging branch to the main branch.
• If all checks and processing passes, we merge to main, if not, we ask you to make changes and create another PR
• Once merged, we can build and publish the book

We will get this going as soon as possible.

p.s Do not make direct commits to main
