 * A task needs two things to be created - a title and a parent report
 * When you create a task report, there are a few things that happen:
 * A task report is created, along with a CreatedReportAction for that new task report
 * A reportAction indicating that a task was created is added to the parent report (share destination)
 * If you assign the task to someone, a reportAction is created in the chat between you and the assignee to inform them of the task
 *
 * So you have the following optimistic items potentially being created:
 * 1. The task report
 * 1a. The CreatedReportAction for the task report
 * 2. The TaskReportAction on the parent report
 * 3. The chat report between you and the assignee
 * 3a. The CreatedReportAction for the assignee chat report
 * 3b. The TaskReportAction on the assignee chat report
 *
 * @param {String} parentReportID
 * @param {String} title
 * @param {String} description
 * @param {String} assigneeEmail
 * @param {Number} assigneeAccountID
 * @param {Object} assigneeChatReport - The chat report between you and the assignee
