neononempty: NonEmpty lists that look [more, like, this]

This package provides NonEmpty, an alternative to the NonEmpty type in base.

It has a few differences from base's NonEmpty:

• It has Show and Read instance similar to that of normal lists

• It has a 100% safe API

• It has a few added/removed/updated functions (see Data.List.NeoNonEmpty's module docs)

• New functions aren't tied to new versions of GHC/base

The show instance is the original raison d'être. When scanning textual data, the brain can interpret uniformity more quickly. Which do you think is easier to scan?

x :| [y, z]
[x, y, z]

Now imagine this in various fields of a large compound structure, and you have two of them, and you're trying to find the difference.

>>> :set -XOverloadedLists
>>> aNonEmpty [1, 2, 3]
[1,2,3]
>>> read "[1, 2, 3]" :: NonEmpty Int
[1,2,3]
