/**
 * This class wraps SimpleRestClient. It provides functionality to
 * catch OAuth errors that may be the result of an expired access
 * token that needs to be refreshed using the user's refresh token.
 * After refreshing the token it retries the request once. If it
 * still fails, the error is thrown up to the caller.
