Self invoking anonymous function assigned to the yournamespacechoice global variable. Serves the effect of keeping all functions and variables private to this function. To expose a function or variable we must explictly return it at the bottom of the function. Remaps jQuery to $.

var yournamespacechoice = (function ($) {
   var publicfunction;

   function privatefunction() {
       // function only available within parent function
   }

   publicfunction = function publicfunction() {
       // public function available outside of this funtion
   };

   // Expose any functions that we need to access outside of this scope. Use yournamespacechoice.functionName() to call them.
   return {
       publicfunction: publicfunction
   };
}(window.$));
