// leftnav.js
// Author: Adam Vickers
// Creates leftside navigation menu for HDS
// Takes an array of values in the form [ "item1", status, "url1",
//										"item2", status, "url2",
//										[ "sub-item1", status, "sub-url1" ],
//										"item3", status, "url3" ];
//
// where "item1" is the text of the link item, status is a value, 1 or 0,
// describing whether the item is in selected state or not,
// "url1" is the link URL. The example contains a nested array (sub-item1...)
// which creates second-tier menu items for the first-tier
// item preceding it.
// 
// This function was created only for the convenience of the UX production team.
// It creates a leftnav menu from an array. It does nothing dynamically
// and is probably of no use in the finished product.
