Bump the version to 1.1.2 in preparation for a release.

Version bump for a release.

Remove reference to api that are "hookable".

These fall down in the face of modules. What's worse, is they
don't fail to build, the fail to apply in some cases, and to
understand it, a developer has to really understand how protocols
work/are resolved/etc.

We also were documenting the wrong method as a hook point.

So, rather than try to document all the things that do/don't work,
just stop documenting it, and allow future changes to not be
required to support it.

Issue apple#773 is open to look at provide better apis in the future for
customizing comparisons.

Bump the version number to 1.0.3.

We'll need a release for Swift 4.1 because of the "near miss" warnings.

Bump version to 1.0.2.

A release will be cut to pick up apple#702.

Fix docs, our tags don't use a leading 'v'.

Update version to 1.0.0
