move example files to examples folder

[HelgeGehring]

I think it would be good to make an examples folder for the examples to let the user have a rather clean notebook to directly start simulating

Can you also update https://github.com/proppy/rad-lab/blob/tuning/modules/silicon_design/scripts/build/cloudbuild.yaml#L39 so that it only copy stuff in examples?

[HelgeGehring]

Why are the examples at all in the bucket? Shouldn't they just be in the notebook? Also, would there be a way to also update them in the notebooks when the image is updated?

@HelgeGehring it seems that /home/jupyter get mounted from the VM in the jupyter container at startup so anything that we would but in /home/jupyter during the image building process would get effectively shadowed by the mount.

Copying them from GCS during the startup script seemed like a good workaround, but maybe provisining a dataDisk would be a proper way to achieve this (assuming it would get mounted instead at /home/jupyter)

Okay, sounds good, then copying the examples (and deleting the folder before) seems like a nice solution!

I've additionally added folders for electronics and photonics (and added there an mmi-tuning-example)
