This revision includes the following changes:

 [1]  app/index.php includes an updated interface with a new set of tiles in the SGA Travel Assistant section
 [2]  need-a-ride/index.php includes a minor change to fit the new security standards of the Ride_Request_Display class
 [3]  ride.css includes new styles to style the splash image on the share-a-ride/index.php page
 [4]  the welcome-icons.png image has been updated to fit the style of the new tiles in the SGA Travel Assistant section of the app/index.php page
 [5]  welcome.css includes an extensive rewrite to re-style the tiles in the SGA Travel Assistant section of the app/index.php page
 [6]  the Ride_Request_Display class now requires that the ID of the current user be passed into the constructor so that users may access content only that is relevant to them. Also, a small change was made to how the city name is filled in by the getWhere() method, since the name of the attribute alias extracted from the database by the super constructor (Ride_Data_Fetch) has changed.
 [7]  the Ride_Data_Fetch class now requires that the ID of the current user be passed into the constructor so that users may access content only that is relevant to them. Also, the SQL query which fetches data from the database has been generalized (instead of selecting the series of attributes which are needed) so that it can work with both ffi_ta_need and ffi_ta_share.
 [8]  the Ride_Request_Process class has been documented
 [9]  travel-assistant.php now registeres an exception for the share-a-ride/index.php page
 [10] the share-a-ride/index.php, along with the supporting Ride_Share_Display and Ride_Share_Process classes, have been added
 [11] gt-r.source.png has been added as the original source image which was used to create the Nissan GT-R icon inside of the welcome-icons.png sprite
