BitmapData creator

/*-----
Author: Tim Henager
Usage:
1. use createFromLibrary() to create a bitmapData object of an embedded image:
var bitmap:BitmapData = createFromLibrary("imageID"); //imageID = linkageID of image to create as bitmapData object

2. Use createFromExternal() to create a bitmapData object of an externally loaded image:
var bitmap:BitmapData;

loadListener.onLoadInit = function(loader_mc:MovieClip) {
//-----this function call is optional-----//
bitmapOptions(matrix, colorTransform, blendMode, smoothing);
//-----returns the bitmapData Object-----//
bitmap = createFromExternal(loader_mc);
};

| Instantiate new instance of DragnDrop class as follows:
| var varname:DragnDrop = new DragnDrop(dragObj, targetObj, _enabled, _alpha, _visible, _play, _mainPlay);
|                                                                                                            |
| Arguments for constructor are as follows:
| 1.) dragObj:Object = Object to drag
| 2.) targetObj:Object =  Target Object
| 3.) _enabled:Boolean =  Disable Drag Object
| 4.) alpha:Number = Change _alpha of Drap Object
| 5.) _visible:Boolean = Visibility of Drag Object
| 6.) _play:Number = Drag Object - play frame number
| 7.) _mainPlay:Number = Main timeline / _level  - play frame number                                         |

IntervalMethodCall

/**

* @class: IntervalMethodCall
* @usage: makes a method call on an object for a given amount of time
* @updates: Version 2.0 will allow for multiple params to be passed
* @param: Constructor: takes an object(generic object or class),
                                       * method(String), params(String), maximum(number) calls and duration(seconds)
* @param: beginInterval [method] begins method call
* @example:
*    var methodCallTest:IntervalMethodCall = new IntervalMethodCall(this, "functionCallTest", "hello World", 12, .5);
*    this.methodCallTest.beginInterval();
*    function functionCallTest(str){
