title: How to access the value parameter of a new object created using JustGage?
body: <p>I didn't go digging, because I don't think it matters what methods and so forth JustGage has, but I have this new object <code>g</code>.</p>
  
  <pre><code>var g = new JustGage({
      id: "gauge", 
      value: 34, 
      min: 0,
      max: 100,
  });
  </code></pre>
  
  <p>My question is how do I retrieve the value parameter later in the script.</p>
  
  <p>I thought that <code>var value = g.value</code> would work, but it doesn't.</p>
  
  <p>Here is a bit of the justgage.js file:</p>
  
  <pre><code> JustGage = function(config) {
  
    if (!config.id) {alert("Missing id parameter for gauge!"); return false;}
    if (!document.getElementById(config.id)) {alert("No element with id: \""+config.id+"\" found!"); return false;}
  
    var obj = this;
  
    // configurable parameters
    obj.config =
    {
      // id : string
      // this is container element id
      id : config.id,
  
      // title : string
      // gauge title
      title : (config.title) ? config.title : "",
  
      // titleFontColor : string
      // color of gauge title
      titleFontColor : (config.titleFontColor) ? config.titleFontColor : "#999999",
  
      // value : int
      // value gauge is showing
      value : (config.value) ? config.value : 0,
  </code></pre>
