class FallbackExecutor:
    """
    A class for managing fallback execution in scenarios where primary functions might fail.

    Parameters:
    - primary_function: The main function to be executed.
    - fallback_functions: A list of fallback functions to be tried sequentially if the primary function fails.
                          Each element is a tuple containing the function and its arguments as a dictionary.
    - error_handler: An optional custom error handler that can be provided to handle exceptions.

    Methods:
    - execute(): Executes the primary function. If it raises an exception, tries each fallback in sequence until successful or no more fallbacks remain.
