This change updates the filename to better reflect its purpose. tryout_pearl.py serves as a test environment for the 'PEARL' reinforcement learning algorithm within the Cooperative Cuisine project.

The additional "env_name" parameter has been added to the game server test setup. This addition is intended to further specify the game environment during testing, improving precision and potentially revealing more detailed results.

Several sections of the codebase have been refactored for maintainability. The 'ORDERS' module has witnessed some cleanups and adjustments in the 'create_init_orders' method. Hooks and associated comments were added in the 'hooks' module for better understanding of code functionality. The 'pygame_2d_vis' script's documentation was also improved for clarity.
