wrap code for CommonJS environments and AMD

[millermedeiros]

avoid generating globals if not needed and help to easily share code between environments.

here is a sample of a wrapper that would run "everywhere":

(function(def){
    def('jlink', function(){

        //jlinq code should go here

        return jlinq;
    });
}(
    // wrapper to run code everywhere
    // based on http://bit.ly/c7U4h5
    typeof require === 'undefined'?
        //Browser (regular script tag)
        function(name, factory){
            this[name] = factory();
        } :
        ((typeof exports === 'undefined')?
            //AMD
            function(name, factory){
                define(name, [], factory);
            } :
            //CommonJS
            function(name, factory){
                module.exports = factory();
            }
        )
));

wrapping the code like this would make it work on node.js, and to be loaded properly by AMD loaders like RequireJS, Dojo (v1.6+), curl.js, etc..
