These are regression tests for the Diderot compiler.  Each test lives in its
own directory under rtest/tests, data files live in the rtest/data directory.
Each test should have a sample output called "correct.nrrd" and a script
to assess the correctness of the output "assess.sh".

To run the tests, use the command scripts/run.sh.  It will produce a report
file the summarizes the results and a log file that contains any output
from running the compiler or program (e.g., error messages).
