updated Kantorowski iframe test files

I've update the kantorowski iframe tests in the ```PrototypeMessageBroker``` folder to put each bric in its own object (except those brix that append to other brix).

I now see what ysahnpark was talking about last week, where either each object needs to cache values usually controlled by a particular bric and therefore must know the relationship between the values, or we would need some method to query a value from a bric in another object. Currently I did what ysahnpark had done and cached the value in the local object (iframe) hardcoding the relationship in each object (so there are 3 different objects where it must be known that ```levo + dextro = 100```).
