This PR seeks to address the design consideration in issue #113.

@gaurav: what content should I include the README, to indicate that the examples for discussion folder has been moved to the DMH repo?

Good question! I would modify the existing README to read something like:

# Examples for discussion

This folder used to contain examples for discussions during the development
of the CRDCH model. They have now been moved to
[the Data Model Harmonization repository](url).

And for the URL, I would use one of the GitHub commit URLs (e.g. https://github.com/cancerDHC/data-model-harmonization/tree/d83c2853ea6cdd8dfbb9204c2cd4c335969660c6/data-examples instead of https://github.com/cancerDHC/data-model-harmonization/tree/master/data-examples) so that we can still point to them even if the folder is subsequently reorganized.

Thanks so much, Sujay!

I've just merged PR #108 and PR #89, so you'll probably need to rebase your changes to main so you move all the files from that directory.
