Added mocha based unit tests for each module Did a bit of cleanup in the modules to remove debug console.log calls Removed the Progress bar in the extractor and the library requirement Promisified the gemini module to make sure it returns the path as a promise instead of just on the cli Fixed gitignore so that it now only ignores the content int the storage directories, and not the whole directories Added neetingReport.json for the LLMs to use
