Version: hdp-global-1.0.0.js
Author: Andrea Ottolina - AKQA
Description: Global Akqa JavaScript functions
-------------------------------------------------------------------------------
jQuery is unsed in noConflict mode due to the Prototype
library used by Sitecore CMS for it's inline page editing
-------------------------------------------------------------------------------
The most efficient jQuery selector is '#id', followed by 'tag.class'
-------------------------------------------------------------------------------
The library is namespaced into the AKQA object.
Mainly is built on Singleton and split in different *Managers* each for
every main functionality

Singleton structure
var myInstance = (function() {
  var privateVar = '';
  
  function privateMethod () {
    // ...
  }

  return { // public interface
    publicMethod1: function () {
      // all private members are accesible here
    },
    publicMethod2: function () {
    }
  };
}());
