    A class that provides a fallback mechanism for executing functions.
    
    This is particularly useful in scenarios where a function might fail due to unexpected errors,
    and you want to handle these failures gracefully by falling back on alternative implementations.

    Attributes:
        primary_func (callable): The main function to execute.
        fallback_funcs (list[callable]): A list of fallback functions that will be tried if the primary function fails.
    
    Methods:
        execute: Tries to execute the primary function and falls back to a series of fallback functions in case of failure.
