Add section for more information

[Saurabh-Suchak]

The existing handbook stands as a valuable resource for anyone who wants to know about carbon models, FLINT, and even the GCBM workflow. It also contains steps for running a GCBM simulation. This handbook can be made even more informational by adding a few more sections to make the process more understandable and relatable. This will help in providing the reader with a little more background information.

The sections I propose to work on are -

• The importance of this project
• The important milestones that were met
• Adding output images and the inference that can be drawn from them
• The challenges that were faced during the implementation
• Process of accurate and reliable data collection
