keep package functions from starting automatically

hey everyone! this should be simple.

i've got a movie clip which i "exported for actionscript" inside of the properties dialog.

this is the code inside of the package that was created to go along with it (MovieClipName.as)

package 
{
     import flash.display.MovieClip;
     import flash.utils.Timer;
     import flash.events.TimerEvent;
     import flash.events.Event;
     import flash.display.Loader;
     import fl.transitions.Tween;
     import fl.transitions.easing.*;
     import fl.transitions.TweenEvent;
     import flash.net.URLRequest;
     import flash.display.Bitmap;
     import flash.trace.Trace;
     public class cont extends MovieClip
     {
          public var mCONTENT:Array=new Array();
          public var mUBTIL:Array=new Array();
          public var NOBAR:Boolean = false;
          public var MASTER:Timer = new Timer(5000,1);
          public var p:Number = 0;
          public var q:Number = 1;
          public var ChurnerI:Tween;
          public var ChurnerII:Tween;
          public var lod:Loader = new Loader();
          public function startSlideshow()
          {
               trace("CONT IS ACTIVE!!!")
               NOBAR=false;
               MASTER.addEventListener(TimerEvent.TIMER, reportProcessComplete);
               MASTER.start();
               loadSequentialPictures();
               function beginSlideshowLoop()
               {
                    if (NOBAR != true)
                    {
                         MASTER.start();
                         loadSequentialPictures();
                    }
               }
               function reportProcessComplete(e:Event)
               {
                    p++;
                    if (p == 2)
                    {
                         p = 0;
                         movePics();
                    }
               }
               function reportMovementComplete()
               {
                    wrapper();
                    beginSlideshowLoop();
               }
               function wrapper()
               {
                    q++;
                    if (q == mCONTENT.length)
                    {
                         q = 0;
                    }
               }
               function loadSequentialPictures()
               {
                    if (mCONTENT.length > 1)
                    {
                         if (mCONTENT is Bitmap)
                         {
                              mCONTENT.y = 0;
                              mCONTENT.width = 857;
                              mCONTENT.height = 512;
                              mCONTENT.x = 857 + 2;
                              stage.addChild(mCONTENT);
                              reportProcessComplete(null);
                         }
                         else
                         {
                              loadSeqPic();
                         }
                    }
               }
               function loadSeqPic()
               {
                    var request:URLRequest = new URLRequest("http://www.jawilsonarchitects.biz/portphot/" + mCONTENT);
                    lod= new Loader();
                    lod.contentLoaderInfo.addEventListener(flash.events.Event.COMPLETE, seqLoaded);
                    lod.load(request);
               }
               function seqLoaded(e:Event)
               {
                    var JohnIII:Bitmap = Bitmap(lod.content);
                    mCONTENT.splice(q,1,JohnIII);
                    mCONTENT.y = 0;
                    mCONTENT.width = 857;
                    mCONTENT.height = 512;
                    mCONTENT.x = 857 + 2;
                    stage.addChild(mCONTENT);
                    reportProcessComplete(null);
               }



               function movePics()
               {
                    ChurnerI = new Tween(stage.getChildAt(0),"x",Regular.easeInOut,stage.getChildAt(0).x,-857 - 2,15,false);
                    ChurnerII = new Tween(stage.getChildAt(1),"x",Regular.easeInOut,stage.getChildAt(1).x,0,15,false);
                    ChurnerII.addEventListener(TweenEvent.MOTION_FINISH, reset);
               }
               function reset(e:Event)
               {
                    stage.removeChildAt(0);
                    reportMovementComplete();
               }
          }
     }
}

most of the code shouldn't matter. i'm new to packages and i just want to know how to keep startSlideshow() from triggering when a new instance of this movieclip is created. i would prefer if something like ThisMovieClip.startSlideshow() had to be triggered. please excuse my dorky labels, etc. thank you!

EDIT: oh! and it would be helpful if you could tell me how to add things to the inside of the movieclip from this package. i assumed adding it to the stage would do the trick but i haven't been able to test to find the right method yet. from the timeline i could just use Movieclip.addChild(picture) but i don't know how to do it from within the package. thanks again.
