(SQL Server) Twitter - Get Follower IDs

Demonstrates how to get a list of follower IDs for a Twitter user. If the number of followers is more than can be returned in a single response, this example will use cursors to page through the followers.

Note: Rate limits will prevent a program from paging through huge lists of followers. In general, a maximum of 16 GET requests (pages) can be retrieved in a short period of time.
