New nodejs module with smarter testing and library functions

I've started re-writing the node module for Balanced as the projects I'm working on require a more versatile and comprehensive solution to working with Balanced from within a node app. Right now it is a work in progress, and is why I have not replaced the lib folder yet.

Please take a look at examples and tests and offer criticisms and ideas to make this become the mainstream module. I will be generating the scenarios soon, and they will be based off the tests code I have already written.
