flatten logic assumes that anything to be flattened is a bag, when it could be
a tuple.

Key: PIG-307
URL: https://issues.apache.org/jira/browse/PIG-307
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: types_branch
Reporter: Alan Gates
Fix For: types_branch
Queries such as:
{code}
a = load 'myfile' using PigStorage() as (name, age, gpa);
b = filter a by name lt 'b';
c = foreach b generate TOKENIZE(name);
d = foreach c generate flatten($0);
store d into 'outfile';
{code}
fail because the flatten statement in d = foreach ... assumes $0 is a bag.
