    A class for creating a limited error recovery planner.
    
    This class helps in managing recoverable states when dealing with operations that may fail.
    It allows setting up multiple recovery points and automatically recovers to the nearest previous state if an error occurs.

    Attributes:
        states: A list of states representing different stages or results of operations.
        current_state_index: An index indicating the current state after recovery actions have been applied.
    
    Methods:
        add_state(state): Adds a new state to the planner.
        recover(): Recovers the system to the nearest previous state in case of an error.

This code defines a `RecoveryPlanner` class that allows adding states and recovering to the nearest previous state in case of an error. The example usage demonstrates how to use this class by simulating errors during operations with states and showing recovery actions.
