/* WHAT THIS SCRIPT DOES
 *
 * 1. Confluence
 *     - Redirect from a Broadbean wiki page:    https://broadbean.atlassian.net/wiki/spaces/ATS/pages/2975662172/iCIMS+integration#Job-Model
 *     - To a Veritone wiki search results page: https://veritone.atlassian.net/wiki/search?text=%22iCIMS%20integration%22&title=true&spaces=ATS
 *     Not perfect, but it gets you most of the way there.
 *
 * 2. Jira
 *     - Redirect from a Broadbean jira ticket: https://broadbean.atlassian.net/browse/INTDIS-500
 *     - To a Veritone jira ticket:             https://veritone.atlassian.net/browse/INTDIS-500
 *     Perfect.

    // and automatically click on the first result *if we've reached there via this script*.

    // Note: The search results page makes an ajax request to:
    // https://veritone.atlassian.net/gateway/api/graphql which returns the actual results.
