 * Search Engine Keyword Highlight (http://fucoder.com/code/se-hilite/)
 *
 * This module can be imported by any HTML page, and it would analyse the

 * the page, by wrapping them around <span class="hilite">...</span> tags.
 * Document can then define styles else where to provide visual feedbacks.
 *
 * Usage:
 *
 *   In HTML. Add the following line towards the end of the document.
 *
 *     <script type="text/javascript" src="se_hilite.js"></script>
 *
 *   In CSS, define the following style:
 *
 *     .hilite { background-color: #ff0; }
 *
 *   If Hilite.style_name_suffix is true, then define the follow styles:
 *
 *     .hilite1 { background-color: #ff0; }
 *     .hilite2 { background-color: #f0f; }
