title: Twitter Bootstrap Popover not working?
body: <p>I have the tooltip for bootstrap working, but anytime I try and initiate the popover instead I get the error <strong>Uncaught TypeError: Cannot read property 'prototype' of undefined</strong> or <strong>Uncaught TypeError: Cannot read property 'Constructor' of undefined</strong> with the following code</p>
  
  <pre><code> Popover.prototype = $.extend({}, $.fn.tooltip.Constructor.prototype, {
  
      constructor: Popover
  
    , setContent: function () {
        var $tip = this.tip()
          , title = this.getTitle()
          , content = this.getContent()
  
        $tip.find('.popover-title')[this.options.html ? 'html' : 'text'](title)
        $tip.find('.popover-content')[this.options.html ? 'html' : 'text'](content)
  
        $tip.removeClass('fade top bottom left right in')
      }
  </code></pre>
  
  <p>I am unclear of the hiccup, because I did see it working previously. Any ideas? Thanks in advance.</p>
