[Tweener] Use var to pass tween property?

[Jeremy Davis]

Below i took values from strings including the property names, pushed to a
function and looped through and added them to an object which then passed to
Tweener afterwards.

import caurina.transitions.Tweener;

var prop:Array = new Array();
prop.push("x");
prop.push("y");
prop.push("time");
prop.push("transition");

var val:Array = new Array();
val.push(100);
val.push(10);
val.push(1);
val.push("easeInOutBack");

buildObj(prop, val);
function buildObj(props:Array, values:Array) {
var myObj:Object = new Object();
for(var i:int = 0; i < props.length; i++) {
myObj[props[i]] = values[i];
}
Tweener.addTween(obj,{base:myObj});
}

Ive actually used xml nodeNames as  property names and passed to a function
to convert to an object. ex:

<x>100</x>
<y>200</y>
<time>1</time>
<alpha>1</alpha>
<transition>easeInOutBack</transition>
