Output Minification (Minifying html,css,js) CI 3.x

You can use tools like grunt to do that. It will take all of your various source css and js files, concatenate them into single files, minify them, etc. No need for a framework to reinvent the wheel when there are existing popular tools that do it. Just use existing technologies that are in wide use...like grunt. http://24ways.org/2013/grunt-is-not-weird-and-hard/
