+### ArcObject.duckInstanceOf(primary:Object,duck:Object)
+Compare two objects to see if the duck object has the same properties bound as functions as the primary object
+```js
+//Example class
+class Test{
+    getSomething(){}
+}
+
+//Two seperate instantiations
+var primary = new Test;
+primary.id = "one thing";
+
+var duck = new Test;

+//Comparison
+(primary == duck); //false
+(primary === duck); //false
+ArcObject.duckInstanceOf(primary,duck); //true
+
+//Change the interface on the primary, so the duck no longer matches
+primary.newFunc = function(){};
+ArcObject.duckInstanceOf(primary,duck); //false
+
+//But reverse the order...
+ArcObject.duckInstanceOf(duck,primary); //true (because we are not comparing if the interfaces are identical, only if the secondary has the same interface as the primary)
