Description

Now that DataBag has an iterator method, it can implement Iterable with no other changes. This would allow bags to be used in a foreach loop like
for(Tuple t : bag) {
// do something with t
}

The attached patch has DataBag implement iterable and converts all bag iterator usages in pig to use foreach loops.
