Global Singleton Usage and OAuth Token Expiration Automation

[nf-developer]

Questions:

• Was this client library designed to be per-request or to be shared among many requests in a global singleton?
• What is the recommended method of handling token expiration?
• To confirm, I don't see this library automatically refreshing the token on EApiV1ErrorCode.InvalidOrExpiredToken so it looks like manually refreshing the token is the only option forward.
• The class TwitterApiv2ReadOnly is missing a reauthentication method that would update the access token. Should I reassign twitterApi.appLogin().readOnly.v2 to my client's instance variable?
