prepare for converting es6 module

[axmand]

Dear Lindsay Kay: thanks for your reply issue #195. I have tried to add rollup and babel plugins in grunt to wrap the entire library like this:

grunt.registerTask("snapshot", ["concat", "yuidoc", "uglify",'rollup']);

rollup: {
            options: {
                format: 'iife',
                moduleName :'xeogl',
                plugins: function () {
                    return [
                        resolve({
                            jsnext: true,
                            main: true
                        }),
                        commonjs(),
                        babel({
                            exclude: './node_modules/**'
                        })
                    ];
                }
            },
            files: {
                'dest':'build/xeogl.rollup.js',
                'src' : 'src/init.js',
            }
        },

and it runs well, the next step is to rewrite some 'class.extend' module as :

class XX extends XXX

if you have better idea， I will be grateful 😃

@MichaelDeBoey actually I'm working on converting xeogl to ES6 at the moment! Will probably have this done sometime next week.

Conversion to ES6 is now complete in this branch: https://github.com/xeolabs/xeogl/tree/es6

I'll merge into master for the next release (v0.9).
