To Web Annotation (from Annotator 2.x...currently)

I've been working on some (deliberately very) basic conversion code to turn
Annotator 2.x JSON output into Web Annotation Data Model.

Here's what I've got so far:
http://bigbluehat.github.io/to-web-annotation/

Code lives at:
https://github.com/BigBlueHat/to-web-annotation

>From what I can tell by using the JSON-LD Playground, the results are
correct:
http://tinyurl.com/pkoygbx
(or http://preview.tinyurl.com/pkoygbx if the short URL ;) )

If nothing else, I figured this would help us get a sense of what a "just
JSON" developer might attempt to do to get their code to "be correct" in
the Web Annotation Data Model world.

The output includes a "-from-annotator-" key (which is ugly on purpose) to
hold the original JSON...as there are some things that just don't translate
yet (mostly the XPath Ranges). Eventually, I hope to get those expressed
somehow and be able to have a lossless conversion, but for now the ugly key
is there as a reminder. ;)

Other things to note:
 - `@id` for the annotation is considered to be relative & uses `
annotation.id` (...which the Annotator dev will need to set...and make it
the actual document name, etc...)
 - there *are* `@id` values "minting" URLs for the sub-graphs (ex: #body,
#selectors, etc.)
    - curious how folks feel about this one
 - having a URL for the JSON-LD context would make this look less...complex

I'll raise some separate issues/thoughts...separately. :)

For now, I'd love feedback from anyone who has time for it!

Cheers!
