1623 // body - Main content of the post
1624 // userId - Not currently used, but would contain the users id that made the post
1625 // userName - Users name that made post
1626 // userAffil - Users affiliation to their school
1627 // public - Boolean which denotes if the post is public to everyone, or private to school users only
1628 // date - Date post was made, updates when any comments are made for the post
1629 // comments - An array of comments which contain a body, userName, and userAffil
1630 // votes - An array of user ids which are the users that voted
1631 // [[ example needed ]]

1634 // [[ bruml: consistent terminology needed ]]
1636 // Posts and comments can be made anonymously. When a post is anonymous, the users info is stripped
1637 // from the post and the userName is set to Anonymous and the userAffil to N/A. This is to allow
1638 // users the ability to make posts or comments that they might not otherwise due to not wanting
1639 // the content of the post/comment to be attributed to them.
1641 // Each time a user connects to the server, it passes through authorization which checks for a cookie
1642 // that is set by Express. If a session exists and it is for a valid logged in user, then handshake.user
1643 // is set to the users data, otherwise it is set to false. handshake.user is used later on to check if a
1644 // user is logged in, and if so display information that otherwise might not be visible to them if they
1645 // aren't apart of a particular school.
1647 // After the authorization step, the client browser sends the lecture id which is rendered into the html
1648 // page on page load from Express. This is then used to assign a 'room' for the user which is grouped
1649 // by lecture. All posts are grouped by lecture, and only exist for that lecture. After the user is
1650 // grouped into a 'room', they are sent a payload of all existing posts for that lecture, which are then
1651 // rendered in the browser.
1653 // Everything else from this point on is handled in an event form and requires a user initiating it. The
1654 // events are as follows.
1657 // A user makes a new post. A payload of data containing the post and lecture id is sent to the server.
1658 // The server recieves the data, assembles a new post object for the database and then fills it with
1659 // the appropriate data. If a user selected for the post to be anonymous, the userName and userAffil are
1660 // replaced. If the user chose for the post to be private, then public will be set to false and it
1661 // will be filtered from being sent to users not logged into and not having access to the school. Once
1662 // the post has been created and saved into the database, it is sent to all connected users to that
1663 // particular lecture, unless it is private, than only logged in users will get it.
1666 // A user votes for a post. A payload of data containing the post id and lecture id are sent along with
1667 // the user id. A new vote is created by first fetching the parent post, then adding the user id to the
1668 // votes array, and then the post is subsequently saved back to the database and sent to all connected
1669 // users unless the post is private, which then it will be only sent to logged in users.
1672 // Similar to the vote event, reports are sent as a payload of a post id, lecture id, and user id, which
1673 // are then used to fetch the parent post, add the user id to the reports array, and then saved to the db.
1674 // Then the report is sent out to all connected users unless it is a private post, which will be only sent
1675 // to logged in users. On the client, once a post has more two (2) or more reports, it will be moved to the
1676 // bottom of the interface.
1679 // A user posts a comment to a post. A payload of data containing the post id, lecture id, comment body,
1680 // user name, and user affiliation are sent to the server, which are then used to find the parent post
1681 // and then a new comment object is assembled. When new comments are made, it updates the posts date
1682 // which allows the post to be sorted by date and the posts with the freshest comments would be pushed
1683 // to the top of the interface. The comment can be anonymous, which then will have the user
1684 // name and affiliation stripped before saving to the database. The comment then will be sent out to all
1685 // connected users unless the post is private, then only logged in users will recieve the comment.
