+ * jQuery Highlight plugin
+ *
+ * Based on highlight v3 by Johann Burkard
+ * http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html
+ *
+ * Code a little bit refactored and cleaned (in my humble opinion).
+ * Most important changes:
+ *  - has an option to highlight only entire words (wordsOnly - false by default),
+ *  - has an option to be case sensitive (caseSensitive - false by default)
+ *  - highlight element tag and class names can be specified in options
+ *
+ * Usage:
+ *   // wrap every occurrance of text 'lorem' in content
+ *   // with <span class='highlight'> (default options)
+ *   $('#content').highlight('lorem');
+ *
+ *   // search for and highlight more terms at once
+ *   // so you can save some time on traversing DOM
+ *   $('#content').highlight(['lorem', 'ipsum']);
+ *   $('#content').highlight('lorem ipsum');
+ *
+ *   // search only for entire word 'lorem'
+ *   $('#content').highlight('lorem', { wordsOnly: true });
+ *
+ *   // don't ignore case during search of term 'lorem'
+ *   $('#content').highlight('lorem', { caseSensitive: true });
+ *
+ *   // wrap every occurrance of term 'ipsum' in content
+ *   // with <em class='important'>
+ *   $('#content').highlight('ipsum', { element: 'em', className: 'important' });
+ *
+ *   // remove default highlight
+ *   $('#content').unhighlight();
+ *
+ *   // remove custom highlight
+ *   $('#content').unhighlight({ element: 'em', className: 'important' });
