Test Push
Refactor of visualization, (near) completion of node drawing, and added getters and setters to Node class.
Now calling the fuser from the visualizer using real graph object. Added some functionality to fuser to dynamically set node colour based on complexity score. Codbase node automatically set to red. Author nodes set to yellow. Added an edge in each node back to parent node in fuser.
Added some test files, some tests, and a calling class to corrdinate calling of our various classes. Modeified the visualizer to run as part of an application instead of running as an applet.
Deleted the caller class. Given the structure of Processing I think we will have to put our main method in the visualizer class and call the parsers and fuser in the setup code. Added code for drawing lines to visualizer.
Added some code to handel arguments which will represent the filepaths of the output files of the two tools.
Added some error handling for calling from the commandline. Just pushing before group meeting.
Modified the layout of the graph. Added tests.
added some tests for fuser
