user_meta.sql may be unnecessary since the info has a one to one
relationship with user.sql

game.sql is a list of some video games.

user_game.sql stores the relationship of a user with a game. could
possibly add more columns for more info like 'favorite', 'mains',
'playing now'.

geocode.js with jquery-ui.js finds the latitude and longitude of a
location entered in the profile editor which is then stored in
user_meta.sql.
