buildscript.js

/*
 * Run:
 * node buildscript.js
 * in the nexus directory to create a basic build of nexusUI.js 
 * with supplrementary element files combined into one file.
 * I've included a minify function but it is not working at the moment
 * so I commented out the function call.
 * 
 * Code written with assist from http://blog.millermedeiros.com/node-js-as-a-build-script/
