Modularized the methods that interact with the twitter stream into a single object called the master controller. Also modularized the methods involved with parsing out coordinates into a globe controller. Began modularizing the methods involved with parsing out and storing hashtags in the database into a database controller.
Added removeDeprecated method to database_controller and called it within the master_controller stream method.
Implemented all garbage collection methods and the method for storing hashtags on the database controller.
Added line graph view to the database controller and globe view to the globe controller.
Made sure that updateCounts, storeHashtags, extractHashtags, removeDeprecatedHashtags, and removeDeprecatedCounts methods are all operationg correctly.
