How to Load and Save individual gameobjects with unitySerializer.

I have a single game object that stores all of my variables that need to be saved. I want to save just that game object and this is my code for it:

 using UnityEngine;
 using System.Collections;
 
 public class GameWideScript : MonoBehaviour {
     public int ReachedLevel = 1;
     public float[] levelTimes;
     public int thislevel;
     public float thisleveltime;
 
     public void Start(){
         DontDestroyOnLoad (this.gameObject);

 //what do i put in the parentheses?
         LevelSerializer.LoadObjectTree ();
         levelTimes = new float[20];
 
 
 
         }
 
     //public int SetVariable
     IEnumerator Wait(float wait) {
         yield return new WaitForSeconds(wait);
         Application.LoadLevel ("GameOverScreen");
     }
             
 
     public void GameOver(){
         StartCoroutine (Wait(1f));
         }
 
     public float[] GetTimes(){
         return levelTimes;
         }
     public void SetTimes(float[] times){
         levelTimes = times;
     }
 
     public void Save(){
         LevelSerializer.SaveObjectTree (this.gameObject);
 
     }
 
 
 }

The only problem I'm having is that I don't know what to put into the LevelSerializer.LoadObjectTree() parentheses. In the Getting Started Guide it puts a variable called yourData. But, I have no idea what the variable yourData is. So what am I supposed to put there to load this gameobject? Thank you!
