Refactoring release 0.1

Hello everyone,

In this lab I had worked on release 0.1 to refactor the code which eventually means to structure code in such a way to look more readable and modular.

3 Feature that has been refactored:

1. Get rid of global variables- I have removed the global variable definitions and encapsulated the logic within functions. The main function is responsible for parsing command-line arguments and driving the program. This makes the code more organized and easier to follow.
2. separate command-line argument parsing from file - In this code, we've separated the file processing logic into a generateHTML function while making minimal modifications. This separation helps improve code organization and readability.
3. reduce code duplication through shared functions, classes- In this code, I added utility functions "readFile" and "writeFile" to handle reading and writing files. This reduces code duplication.

Bugs and error: While completing i do found some bugs such as for exit code and parsing error for TOML format.

Conclusion: Through this journey I learned the importance of maintaining neat and clean code which help other developer to work on project and further helps to find minor bugs which can be removed from project.
