WIP: Fixes for Finals

[georgetayqy]

Points to Work On

1. Exporting Function to export news content, rather than just terms
2. Too much scrolling to input parameters

[georgetayqy]

Updates

1. Currently, exporting for other file formats is being implemented. Future implementation will allow users to append multiple datasets together and to return them in an XLSX format which supports multiple datasets in the same file
2. Parameter input has been condensed into rows and made more compact. Text clutter has been moved to expander widgets or help pointers within widgets

Updates 12/01

1. No new functions are to be added, hence advanced functionalities have been removed

Updates 25/01

1. Model Trainer Package to be moved to a separate repository in the near future, leaving on the initial set of functions presented in the Preliminary rounds
2. Currently working on a way to condense the outputs into columns (especially the outputs from modules that spits out a lot of data)

Final Fixes for the App should have been fully implemented in this Pull Request. Futher updates shall be made to fix smaller bugs that were not found in this round of debugging and feature enhancement.
