A NonEmptyMap Implementation.

This package intends to allow general use of a NonEmptyMap which is very beneficial as sometimes you want the functionality this provides.

Data.Map.NonEmpty - NonEmptyMap

This map implementation is a NonEmptyMap that can be used where that is necessary. Hopefully slowly porting over more and more functions from the containers libraries.

There is a lot more work to be done, so please feel free to help get this operational.
