Improved zero shot 'forced' categorisation and prompts

Allowed for manual modification of output topic table. Did some fixes to deduplication and Excel file input. Allowed for General topic specification in zero shot topics

Added options to use different sentiment categories. Can ask for more concise summaries.

Refactor app.py and related modules for improved topic extraction and summarization. Updated UI prompts for clarity, enhanced file upload functionality, and added error handling in AWS file uploads. Introduced new functions for converting response text to markdown tables, creating general topics from subtopics, and improved overall code structure for better maintainability.

Corrected prompt. Now runs Haiku correctly

Can now specify root path for app with an environment variable

Added support for using local models (specifically Gemma 2b) for topic extraction and summary. Generally improved output format safeguards.
