/*
* 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' });
