title: Extend a jQuery plugin
body: <p>Say I have a jQuery plugin like $.abc = function() {}. Now I want to provide an extra module which uses the same scope as $.abc and extends its functionality. For e.g. in my abc plugin I will check if say a variable mod1 = true; if its true, then I will automatically call thoso functions of mod1.</p>
  
  <p>My question is how do I write mod1 so that it can share the same namespace as my base plugin and I am able to call it from my plugin e.g. mod1.getFiles();</p>
  
  <p>Thankyou for your time. Sorry if this is not very clear. I will explain again if you have any questions.</p>
  
  <p>UPDATE: How do I call function test of pluginbar?</p>
  
  <pre><code>$.fn.pluginFoo = function() {
      ...
       CALL FUNCTION TEST OF PLUGINBAR
      ...
  };
  
  $.fn.pluginBar = function() {
      ...
      function test() {
          alert('this is a test'); 
      }
      ...
  };
  </code></pre>
