This revision includes the following changes:
 - [1] browse/index.php was updated to use the new City and State classes, instead of the deprecated Trip_Info class. It can now provide a friendly "No Cities are Available" message if a user clicks on a state with no origin cities available, instead of redirecting the user to the plugin home page.
 - [2] app/index.php no longer includes an alert message if the user successfully posted or updated their trip information. A future release will direct the user to their trip details page.
 - [3] The FFI_Map_Maker.js jQuery plugin has been *slightly* modified to include an extra "/" at the end of the URL which appear inside of the Google Maps balloons on the plugin home page. Why did I so that??? Seriously...
 - [4] browse.css includes one new style for the browse city/state page to use whenever there are no available cities associated with a particular state.
 - [5] global.php corrected an issue where jQuery was being loaded AFTER the dependent Twitter Bootstrap library was loaded. Bootstrap is dependent on jQuery. It also has been properly commented, and utilizes jQuery 2.x.
 - [6] The City class has been added in this revision and will continue to grow in the coming revisions. For now, it can retrieve all origin cities associated with a particular state, when given the state URL. This method was transferred from the new deprecated Trip_Info::getOriginCitiesByState() method.
 - [7] The new State class includes several methods which were transferred over from the deprecated Trip_Info class, such as the exists(), getInfo(), URLPurify(), and getOriginCitiesByState() methods (renamed to getOriginCities). See the comments on the Trip_Info class for more details.
 - [8] The deprecates Trip_Info class was renamed to State, and then copied and pasted to State.php. Several modifications to the Trip_Info class were made before the transfer. For example, the namespace was corrected from FFI\BE to FFI\TA, the exist() method was added to check the existence of a US state, and getInfo() was also added to get all available information about a particular US state.
 - [9] The exceptions package was added to handle several specific errors the application may encounter. At this point, a Base_Exception class exists, and extending it is an Invalid_State_Exception class which is thrown when the user attempts to browse for a US state which does not exist.
