""" Work in progress
Plan:
   Modded version of graph-embeddings.py
   Just to see if using different CLIP module changes values significantly
   (It does not)

   It does have the small bonus feature of being able to accept a purely
   numerical tokenid in liu of a number, if you use the syntax,
   "#345".
   You can input a text string, or a single numeric code, per input

   This code requires
       pip install git+https://github.com/openai/CLIP.git
