Safe self invoking function wrapper! Suuhhweet! This is actually a way to create a type of Namespace in Javascript

SelfInvokingFunctionWrapper.js

//version without passing in parameters that are not available in the function scope
;(function(){
  
  //code here
  
  //why the leading semi colon?
  // this is a safe way to keep from having conflicts with other code that uses the same
  // self invoking functions but left off the colon
  
})();
