Creates a Document Object Model based on input HTML file and performs manipulations on the file by manipulating the tree. This was yet another student assignment in Rutgers' CS112 (Data Structures) course. The driver was written by course instructors, while the bulk of methods in src/structures/Tree.java were written by Daniel Ayoub. These methods include build, replaceTag, boldRow, removeTag, and addTag, including all helper/recursive methods that these methods call.
