Some Classes don't show inline examples

[toddjordan]

Some of the inline examples aren't showing up because their names don't match up with the name in mappings.json

doc name	mappings name
Adapter	TestAdapter
EmberObject	Object
ContainerProxyMixin	none
EmberArray	Array
EmberError	Error
EventTarget	none
Promise	no localName
Router	EmberRouter

• [x] Adapter
• [x] EmberObject
• [x] ContainerProxyMixin
• [x] EmberArray
• [x] EmberError
• [x] EventTarget
• [ ] Promise
• [x] Router

Promise is interesting... its the only place where a class is not using the default import, and instead we want folks to use import { Promise } from 'rsvp';. Interesting that we didn't do import Promise from 'rsvp/promise'; instead.

Regardless, working on a PR to do some more smart reading of mappings.json to detect non-default class imports.
