I have packaged a `Makefile`, `Gruntfile` for building and testing, and `npm` scripts point to those.

Available commands are:

- `make` (Aliases: `npm run-script preinstall`) : 
  Compiles the C++ code into node extension.

- `make clean` (Aliases: `npm run-script preuninstall`):
  Removes the `build` directory.

- `node test` (Aliases: `make test`) : 
  This is for visual testing rather than unit testing. 

- `grunt test`  (Aliases: `grunt`; `npm test`): 
  This is for unit testing.
