    A class for creating a fallback mechanism in an execution context where primary operations may fail.
    
    This implementation provides a simple yet effective way to handle errors by attempting
    a secondary operation if and when the primary one fails.

    Attributes:
        primary_executor (Callable): The function or method that is the main executor.
        fallback_executor (Callable, optional): The function or method that acts as a fallback in case of an error during `primary_executor`.
        recovery_function (Callable, optional): A function to perform any necessary cleanup or recovery after a failure.

    Methods:
        execute: Executes primary executor. If it fails, attempts the fallback executor.

This example demonstrates a `FallbackExecutor` that can be used to manage errors in function execution. In this case, it handles a potential division by zero error by providing a safe version of the `divide` function as a fallback.
