0.2.0.0

• Made NMap and NSum polymorphic over the kind of the key. (Perhaps 'Natural' keys would be useful as well.) This is a breaking API change, because the qualifier for the kind of the key must go before the qualifier for the typelevel lists, potentially breaking TypeApplication uses.
• Add Eq and Ord instances for NMap and NSum
• Add a testsuite

0.1.0.1

Quickfix for an oversight in the uninsertSum function that broke splitSum.

0.1.0.0

Initial release. Expect the public-facing API to change as the library is reworked.
