- Added a function to display memory statistics.
- Altered cpc.scm a little bit; I commented out some of the helper
  functions for the sake of ease of loading.
- Beginning work on a metacircular evaluator.
- Added an idea for optimizations that I had into README.pod.
- Copied scheme.pl to metacircular.pl. I'm just going to modify the
  existing syntactic analyzing code.
- I've finished the metacircular evaluator, but I think there's a bug
  in the function call code.
- Condensed some of the code in scheme.pl
- Enhanced the 'while' special form in both interpeters. This /might/
  make the code slightly slower; I'll have to run some profiling.
- Updated the README file.
- Added redunant ! (factorial) function for sake of typing.
- Changed all function lambda expression that were undef to the name
  of the function in both metacircular.pl and scheme.pl.
- metacircular.pl passes most of the tests. I don't have the patience
  to wait for it to pass all the tests. I stopped after it passed the
  single recursion test.
