Add Mocha to package.json

I had to rename packages.json to package.json. Apparently I can't read. Once
that worked I added Mocha to the devDependencies.
Added devDependencies node

Added mocha to devDependencies.
Add makefile

Created a simple make file to run tests.
Remove packages.json

This file is named incorrectly. Renamed.
Add script for 'npm test'

Added 'npm test' to the script section of package.json. This is currently hard
coded to a specific working directory. This needs to change.
