This module uses the Python Reddit API Wrapper (PRAW) to search recent reddit comments
for the ClashCaller! string. If found, the username, comment time, message, and
expiration time (if any) are parsed. The default, or provided, expiration time is
applied, then all the comment data is saved to a MySQL-compatible database."""
