/**
 * reportbot.js
 *
 * Created by Calvin Tong on 11/10/15
 * Updated by Joseph Zhong on 12/20/15
 *
 *
 * This is the ReportBot.
 * Implementation and interaction involves invoking a Heroku-deployed Nodejs
 * application, updating and reading a ParseDB for people and reports,
 * parsing a slack message, determining whether the message is a report
 * invocation, and then appropriately message that person's new report count.
 *
 * Example Invocation:
 *    report Joseph
 *    >> Joseph has been reported 65 times
 *
 * Current known issues:
 *    Slack on mobile causes syntax errors because of an extra space (11/20)
 *    Isotopes refactored to uppercase form -- should be lowercase (12/20)
 *
