@graph container support (#549)

* Add @graph container tests.

* A couple of more graph expansion and compaction tests for corner cases.

* Add tests for expanding and compacting named graphs where term definition includes `@graphid`.

* Expand and compact `@container: @index` where value is a graph.

* Disable highlight.js, and update our use of the "highlight" class to "hl-bold". This makes rendered JavaScript examples slightly less pretty, but restores the specific highlighting used with "****" in examples.

* Sort many definition lists automatically using `@data-sort`.

* Add @Version to context definitions in examples using 1.1 features.

* Syntax updates to describe Graph Containers.

* Add inline ednotes for places that are affected by issue #480.

* Add compaction and expansion tests for `@graph` with `@index` and `@id`.

* Add syntax for graph maps and API algorithms for all graph containers.
