  ## each subfolder:
  #### Step 1. Go to a subfolder
  #### Step 2. Run the XML sitemap extractor python script, outputting two csv files.
  #### Step 3. Take the simple one of those sitemap csv files, rename it to a text file
  #### and move it to original working directory.
  #### Step 4. Then run the main AI + NLP keywords finder python script, outputting a
  #### final csv file (Optionally an HTML file too. To output the html file too, comment-out
  #### the block in this program where the html file is deleted.)
