OpenAPI Playground fix

0.17.5

fix open API playground.

Bug Fixes and test additions (OpenAPI support only)

Fixed a few bugs, including Included support for documents. Added some tests around that and more.

OpenAPI Bug fixes and added support for Operation.RequestBody

Now a requestBody key can be specified on an OpenAPI "operation." Like most of the rest of the OpenAPI support, this is currently untested.

This does not affect the stability of the rest of the JSONAPI project.

Fix another dictionary-as-array bug.

0.17.2

Fix a third dictionary-as-array bug

Fix two bugs

Fix:

1. OpenAPI schema for Entity included id when the Entity was "Unidentified."
2. OpenAPI schema was invalid due to two Dictionaries getting encoded as arrays.

Bringing in a lot of untested OpenAPI Stuff

Bringing a lot of untested and far from completed OpenAPI stuff into the mix.

1. It is still useful in the right context.
2. It does not touch or destabilize the JSONAPI work.
3. It all exists within the JSONAPIOpenAPI framework and does not even need to be built.

Fix OpenAPI Date format error.

Fix bug causing encoder for OpenAPI node with example to not get used everywhere it was applicable.
