- Fixed broken WHILE special form in metacircular.pl. Program still
  gets wedged during CLOSURE-TESTS, but it might just be because this
  compe is really slow.
- Added a command line option to pipe output of memory statistics to
  file. This will need a bit of cleanup.
- Modified the test macro so that the name of the test is outputed as
  the test is being run. This might not work...
- Updated the README to reflect changes to the interpreter.
- Added echo file command line option for the metacircular evaluator.
- Updated the README to reflect this change.
