```python
class FallbackExecutor:
    """
    A class that provides a fallback mechanism for executing operations,
    recovering from errors by falling back to a default or alternative function.
    
    Parameters:
        - primary_function (callable): The main function to execute.
        - fallback_function (callable, optional): The function to use in case of an error with the primary function. Defaults to None.

    Example usage:

    >>> def divide(a: float, b: float) -> float:
    ...     return a / b
    ...
    >>> def safe_divide(a: float, b: float) -> float:
    ...     try:
    ...         return divide(a, b)
    ...     except ZeroDivisionError:
    ...         print("Cannot divide by zero!")
    ...         return 0.0
    ...
    >>> fallback_executor = FallbackExecutor(divide, safe_divide)
    >>> result = fallback_executor.execute(10, 2)  # Normal execution
    5.0
    >>> result = fallback_executor.execute(10, 0)  # Error and fallback
    Cannot divide by zero!
    0.0
