Update - Angular Dependency Injection

[AbdellaToronto]

Angular Dependency Injection

• Remove references to AngularJS

Angular’s DI

@Inject() and @Injectable

• Remove “There is a lot to decorators.”

Avoiding Injection Collisions: OpaqueToken

• This is deprecated as of Angular 5. Should mention InjectionToken instead

Removed the opaque token link until that is properly re-written
