Working on getting Embeddings from NOC files

[shiffman]

This is using the markdown files and chunking by section. Another option is to use the entire chapter. I would also like to create separate embeddings for each code example. Steps to do this are:

1. Consolidate all code examples into one sketch.js file each.
2. Use a language model to write an description of what the example does.
3. Get an embedding of the description. (or would it work to just get an embedding from the code itself?)
