// GHSnavigation.js - displays the site navigation with a line highlighted: identified with option number passed
// A navigation line item consists of a localNavOption, optionURL and an if-else block for a specific option number
// Note: Option number zero is the first option - determined by Javascript array definition

// This script builds list items for an un-ordered list in the following fashion (the CSS class is determined by
// the option number passed by the calling HTML page):
//   <li><a href="somePage.html" class="highlight">FAQ</a></li>
// or
//   <li><a href="somePage.html">FAQ</a></li>
