Using a class and naming it "PocketApp" serves several important purposes in this script.

Why Use a Class?
1. Encapsulation: A class allows you to group related functionality together. In this case, the "PocketApp" class encapsulates all the methods related to interacting with the Pocket API, like adding articles and handling exceptions.
2. Reusability: By defining a class, you can create multiple instances of "PocketApp" if needed, each with its own state.
3. Organization: Organizing code into a class structure makes it easier to manage, read, and maintain. It keeps related functions (methods) together, which improves code readability and manageability.
4. State Management: A class can maintain state across methods. For example, the "PocketApp" class keeps track of the number of successful saves and failed saves, which wouldn't be as straightforward with standalone functions.

Why "PocketApp"?
1. Descriptive Naming: The name "PocketApp" clearly indicates that this class is designed to interact with the Pocket API. It gives a good idea of what the class does at a glance.
2. Namespace: Using a class name like "PocketApp" helps avoid naming conflicts with other classes or functions that might be present in your script or imported libraries.
3. Conventions: Following naming conventions (such as using CamelCase for class names) makes your code consistent with Python standards, which is helpful for readability and maintenance.

Example Benefits
- Encapsulation: Methods like "add_article", "handle_pocket_exception", and "add_articles_from_file" are all part of the "PocketApp" class, which logically groups them together.
- State Management: Attributes like "failed_saves" and "success_saves" maintain the state of the application, allowing you to track the progress of URL additions.
- Clear Structure: When you read the script, you can immediately see that the "PocketApp" class is central to the application's functionality, making it easier to understand the code structure.
