/**
* Seperate single tweets into an individual collection, combine threaded
* Tweets / Tweet replies into combined collection.
*
* Application-only authentication Tweets from a designated user timeline.
* Twitter offers applications the ability to issue authenticated requests on
* behalf of the application itself (as opposed to on behalf of a specific user).
* Twitter’s implementation is based on the Client Credentials Grant flow of
* the OAuth 2 specification. Note that OAuth 1.0a is still required to issue
* requests on behalf of users.
* With Application-only authentication you don’t have the context of an
* authenticated user and this means that any request to API for endpoints that
* require user context, such as posting Tweets, will not work. However, the
* set of endpoints that will still be available can have a higher rate limit.
