  - Updated TreeView to allow for embedded tree views   - Added useful external methods (expand, collapse, etc.)   - Used tkFileDialog   - Fixed printing to print the entire canvas   - Added docstrings   - Added print_tree, which prints a tree to a file, hopefully     without ever opening a new Tk window.  (File contains ps)
