• Move lark known tokens to a separate file
  • This script gets called in the workflow to verify that the known tokens list is up to date
• Created code_block_syntax_generator.py to generate js lists of token types for codeUtils and sandbox
• Changed syntax highlighting for code blocks to highlight and word before parentheses as functions
  • for example: node() gets highlighted
