- Added a .gitignore file that should ignore most non-related nodejs files.
- Created tests for this module.  These tests are meant to be run via Mocha as
  specified in the Makefile.  To run, use 'make test'.
- Updated package.json to include the development dependency for Mocha under
  "devDependencies".
