> If you define two PluckTuples with different regexes, and use them together,
> they will overwrite the regex field of one another's (this will not affect
> cases where non-regex prefixes are used).
> Example (from testOutput in TestPluckTuple.java, modified)
> a = load 'a' using mock.Storage();
> b = load 'b' using mock.Storage();
> c = join a by x, b by x;
> define pluck1 PluckTuple('a::.*');
> define pluck2 PluckTuple('b::.*');
> d = foreach c generate pluck1(*) AS pluck1, pluck2(*) AS pluck2;
> Expected:
> ((1,hey,2),(1,sasf,5))
> ((2,woah,3),(2,woah,6))
> Actual:
> ((1,sasf,5),(1,sasf,5))
> ((2,woah,6),(2,woah,6))
