> POForEach has lot of code to handle flattening (cross product) of the fields 
> in the generate. This is relevant only when atleast one field in the generate 
> needs to be flattened. If all fields in the generate do not need to be 
> flattened, a more simplified and hopefully more efficient POForEach can be 
> used.
