added commander.js for help and version number

[YusufMohamed]

i'm facing some problems with coffeescript as i can't get the cli to work like vispack install plugin for 2 reasons:

• i can't make shebangs #!/usr/bin/env node in top of vispack.coffee as the there is // compiled with coffeescript commend in first line
• when i try npm install -g to install the vispack package globally. node can't find the .js files to link as it only finds the coffeescript files. we need something like preinstall script.
  this also should resolve There is no cli usage or version sections #6 .

you should grunt build the js file from coffee file, and fix the executable js file location from package.json file.

I think this StackOverflow Answer solves your problem.
