* Add H and Section components for context-aware headings
* Switch to using the new context-aware heading and section components
* Style header by class name, not heading level
* Add our client dir to the modules list for Jest
We already have this setting in webpack, but Jest doesn’t pick up on that
* Add Jest testing with Gutenberg as a dependency
* Add test using Enzyme
* Update for “element” moving
Something also must have moved api-request, so we mock that import now
