           │ > Build a model for the classic dining philosophers problem: Five philosophers are sitting at a round table with a bowl of rice in the middle. For the philosophers (being a little unworldly)     │
           │ life consists of thinking and eating (and waiting, as we will see). To take some rice out of the bowl, a philosopher needs two chopsticks. In between two neighboring philosophers, however, there │
           │ is only a single chopstick. Thus, at any time only one of two neighboring philosophers can eat. Of course, the use of the chopsticks is exclusive and eating with hands is forbidden.  Write a     │
           │ property that checks whether deadlock is possible. Use the variable names phil1, phil2, phil3, phil4, phil5, chopstick1, chopstick2, chopstick3, chopstick4, and chopstick5.                       │

           │ This Python code extends the `Module` class to represent the dining philosophers problem using boolean variables to indicate whether each philosopher is eating (True) and whether each chopstick  │
           │ is available (True). The `next` method simulates the action required for a philosopher to start or stop eating based on the availability of neighboring chopsticks. A property method              │
           │ `deadlock_possible` checks if a deadlock can happen by assessing if all chopsticks are being held simultaneously, thereby blocking any philosopher from starting to eat. Adjust further according  │
           │ to simulation needs and detailed implementation of the next state transitions for all philosophers.                                                                                                │
