Implement back button functionality for directory navigation 

The back button functionality was added to the web application. Now users can navigate directories back and forth, improving user experience and interaction. This new feature is achieved through a 'handleBack' function in the 'back.js' file which listens to the click event on the 'Back' button. When clicked, it adjusts the current directory and navigates the application to the parent directory. This is especially crucial for a software that has a file system or explorer-like structure. The 'Back' button was also modified in 'index.html' to support this functionality and the 'handleBack' function was called in the 'Main' function in 'index.js' to initialise it at the start.
