'Fetch a sequence of user ids, one for each friend.

user.
Args:
user_id:
The id of the user to retrieve the id list for. [Optional]
screen_name:
The screen_name of the user to retrieve the id list for. [Optional]
cursor:
Specifies the Twitter API Cursor location to start at.
Note: there are pagination limits. [Optional]
stringify_ids:
if True then twitter will return the ids as strings instead of integers.
[Optional]
count:
The number of user id\'s to retrieve per API request. Please be aware that
this might get you rate-limited if set to a small number.
By default Twitter will retrieve 5000 UIDs per call. [Optional]
total_count:
The total amount of UIDs to retrieve. Good if the account has many followers
and you don\'t want to get rate limited. The data returned might contain more
