Guys, I know this must be a common use case, but how do you explode and
implode in pig?

so, I have a file like this...

1, asdf
2, qewrty
3, zcxvb


and I want to apply an explode operation to it:

1, a
1, s
1, d
1, f
2, q
2, e
2, w
2, r
2, t
2, y
3, z
3, c
3, x
3, v
3, b

and after some work... I have this file:

1, aa
1, ss
1, dd
1, ff
2, qq
2, ee
2, ww
2, rr
2, tt
2, yy
3, zz
3, cc
3, xx
3, vv
3, bb


and I want to perform an implode:

1, aassddff
2, qqeewwrrttyy
3, zzccxxvvbb


well, obviously this is a dumb example, but I'd like to do those things. Can
somebody help me with this? I looked in the piggy bank and didn't see
anything that would do this for me.

Thanks!
