I would like to request that multimap be added to the data library.  As a
C++ programmer (and a complete Haskell newbie), I find myself frequently
using std::multimap from the STL.  However, as I'm moving my programs to
Haskell, I'm having to do hacks such as a maps of keys to sets of values.
 I noticed that DData is under consideration, which has a multiset, so
why not a multimap?  I would implement it myself, but as I said, I am
just learning FP.
