LFPy tutorial to run at the EBRAINS collaborator

LFPy is preinstalled at the EBRAINS collaboratory, and running these exercises should therefore be easy, just click this button:

This requires a free EBRAINS account, which can be made here: https://www.ebrains.eu/page/sign-up

An alternative to the button above is to do this all manually:

Recipe:

1. Go to https://wiki.ebrains.eu/bin/view/Main/, log in, and click "Collabs" on the top right
2. Click the button "Create a collab"
3. Make up some personal collab name ("Mary_testing_LFPy"), and set visibility to "Private". Click "Create Collab"
4. Press "Lab" on the left, and choose Execution Site. Which site you chose should mostly be irrelevant.
5. In the Jupyter Notebook, press the button on the leftmost bar that is named "Git" (hover over with the mouse to see the name).
6. Press the button "Clone a Repository", and give the URL https://github.com/LFPy/tutorial_at_EBRAINS/
7. Under the folder "tutorial_at_EBRAINS", you should now find examples and exercises. Find and click on a Jupyter Notebook
8. When it opens, make sure the Jupyter Notebook kernel (top right on the Jupyter notebook) is set to "EBRAINS-23.09" or newer

You should now be able to play with the different exercises and examples.
