Read text file to get 2D array

Gday all (again)

Another Q relating to the maze game I am working on:

I have made a maze game that creates levels from scripts rather than constructing it by manually placing the walls down. Initially I just have a Terrain and an empty Game Object called Startup with scripts attached. The maze load script loads the maze from an array and places the player at start location, exit trigger at the exit and walls etc down according to the characters in the array.

Currently I specify the array inside the maze load script (testing and proof of concept) and it works great.

What I WANT to do is read a text file to set up the array... This will allow people to make their own and play them.

What I am looking to do is read a text file and save each line as an array of single characters. I then want to put all the individual line arrays into another array (creating a 2D array)

Code as follows:

 #pragma strict
 
 var exitPrefab : GameObject;
 private var thePlayer : GameObject;
 var thePlayerPrefab : GameObject;
 var wallPrefab : GameObject;
 private var escMenu = false;
 
 var rowOne =   ["8","E","8","8","8","8","8","8","8","8","8","8","8"];
 var rowTwo =   ["8"," ","8"," "," "," "," "," "," ","8","Z"," ","8"];
 var rowThree = ["8"," ","8","8","8","8","8"," ","8","8","8"," ","8"];
 var rowFour =  ["8"," ","8"," "," "," "," "," ","8"," ","8"," ","8"];
 var rowFive =  ["8"," "," "," ","8"," ","8"," "," "," "," "," ","8"];
 var rowSix =   ["8","8","8","8","8","8","8","8","8","8","8","8","8"];
 
 var mazeArray = [rowSix, rowFive, rowFour, rowThree, rowTwo, rowOne];
 
 private var iylength = mazeArray[0].Length; //13
 private var ixlength = mazeArray.Length; //6
 private var thePlayerLoc;
 
 function Start () {
     if (exitPrefab == null){ exitPrefab = Resources.Load("PrefabExit");}  
     if (wallPrefab == null){ wallPrefab = Resources.Load("WallPrefab");}  
     if (thePlayerPrefab == null){ thePlayerPrefab = Resources.Load("PlayerPrefab");}  
     
     SetupMaze();
 }
 
 function Update () {
 if (Input.GetKeyDown(KeyCode.Escape)) {
         if (escMenu == true) { 
             escMenu = false;
             }
         else { 
         escMenu=true;
         }
     }
     
     if (escMenu){Screen.lockCursor = false;}
     else {Screen.lockCursor = true;}
 }
 
 
 function SetupMaze(){
     for (var ix = 0; ix < 13; ix++){
         for (var iy = 0; iy < 6; iy++){
             if (mazeArray[iy][ix] == "8"){
                 Instantiate(wallPrefab, Vector3 (ix+50.5, 0.5, iy+50.5),  Quaternion.identity);        
             }
             
             if (mazeArray[iy][ix] == "Z"){
                 thePlayer = Instantiate(thePlayerPrefab, Vector3 (ix+50.5, 1.5, iy+50.5),  Quaternion.identity);
                 thePlayerLoc = Vector3 (ix+50.5, 1, iy+50.5);
             }
             
             if (mazeArray[iy][ix] == "E"){    
                 Instantiate(exitPrefab, Vector3 (ix+50.5, 0.5, iy+50.5),  Quaternion.identity);        
             }
         }
     }
     yield;
     thePlayer.transform.position = thePlayerLoc;
 }
 
 
 
 function OnGUI () {
     if (escMenu == true) {
         if (GUI.Button (Rect (Screen.width/2-50,Screen.height/2,100,20), GUIContent ("Quit"))){
             Application.LoadLevel (0);
             }
     }
 }

Questions:

1. How do I read a text file to individual arrays (I have searched but not been able to find anything that suits what I need)

2. Is there a way to test in the unity editor that will work when built? (ie. I am assuming I will have to add another folder once it is built as unity combines everything when it builds? But wont this mean the code that works when testing in unity will have to be changed to work when it is built?)

3. Is there a better way to compare the arrays? (the rowOne - rowSix is just for testing, When I can get it to read from text files I will make that part dynamic)

Assistance is GREATLY appreciated!!!
