   * Increments the progress value of a numerical achievement by a specified amount.
4. **AddValueToAchievement (string achievementName, int amount)**
   * Increments the progress value of a numerical achievement by a specified amount using achievement's name.
5. **UnlockSecretAchievement (string nameOfAchievement)**
   * Unlocks a secret achievement by its name.
6. **UnlockSecretAchievement (int id)**
   * Unlocks a secret achievement by its ID.
7. **CheckForCompletion (Achievement achievement)**
