This revision includes the following changes:
 - [1] book/index.php was updated to include the purchasing jQuery plugin, and now utilizes the new Course class, instead of the old Book_Courses class. The address to the course icon was updated to the newest standards.
 - [2] browse/index.php was massively rewritten to include a grey sidebar on the left side of the page. The course breakdown by section has been rewritten to use an interactive graph to break down the course numbers and sections into a visually compelling experience.
 - [3] The arbor package was added to include the entire ArborJS library for use on the browse page.
 - [4] course.css was updated to re-style the splash section of the browse page. It has been shortened and the <h2> element inside of it will now only display on a tablet. The styles for the grey sidebar has been added, and the styles for browsing the courses has been removed since the ArborJS graph now serves this purpose.
 - [5] main.css has updated the width of the text in the splash container objects, and vertically centers the positioning of the <h2> tags inside of these containers.
 - [6] main.min.css reflects the changes made to main.css.
 - [7] browse.png is a sprite added for display in the sidebar of the browse page.
 - [8] The large data tiles have been updated to (ironically) a smaller size to better fit the given space in the updated design of the browse page.
 - [9] The Book class had its quickView() method and documentation updated. This method is no longer a stub, but a fully functional method which will print out a quick preview of a book.
 - [10] The Book_Details class had its SQL query updated to fetch data from the newly re-structured database.
 - [11] The Book_Overview class had the getNumbersWithBooks() and getRecentBooksInCourse() methods have been transferred out of this class to the Course class.
 - [12] The Course class  - had the getNumbersWithBooks() and getRecentBooksInCourse() methods have been transferred from the Book_Overview class into this one. The URLPurify() method was also added to purify the title of books for use in URL.
