```python
class FallbackExecutor:
    """
    A class to handle tasks where a primary executor may fail due to errors or other issues,
    allowing for a fallback mechanism.

    Parameters:
        - primary_executor (Callable): The main function that should execute the task.
        - fallback_executor (Callable): The secondary function used as a backup if the primary fails.
        - max_retries (int, optional): Maximum number of times to attempt execution before giving up. Default is 3.

    Methods:
        - execute: Attempts to run the task using the primary executor and handles errors by falling back
                   to the fallback executor or retries based on failures.

        Execute the task using the primary executor. If an error occurs, attempt to use the fallback executor.
