Remove any output on successful parse
Return 0 for success, 1 on error
Add ability to handle command line options
Make error outputs somewhat more informative

Output the class name of the exception that was caught.

Add script to run functional tests
Add test programs to test directory
Add makefile to layout graphs of reference output

The reference outputs will be version controlled, since they are used to
validate the test results. Provide a script to generate images from the
reference outputs so a developer can easily check the test results
visually.
Add cse reference output
Update .gitignore

This will ignore *.png files and files in the test/results directory.
Add COPYING to test input directory

This it to credit that most of the tests were not authored by me.
Indicate which tests were authored by myself
