/**
* The $navItems variable is an array of objects, each representing a nav menu item.
* It is a "flattened" one-dimensional list of all nav items -- it is not hierarchical.
* However, a nested nav menu can be constructed from this "flat" array by
* looking at various properties of each item to determine its place in the hierarchy
* (see below, for example $navItem->level, $navItem->subDepth, $navItem->hasSubmenu, etc.)
*
* Items in the array are ordered with the first top-level item first, followed by its sub-items, etc.
*
* Each nav item object contains the following information:
* $navItem->url : URL to the page
* $navItem->name : page title (already escaped for html output)
* $navItem->target : link target (e.g. "_self" or "_blank")
* $navItem->level : number of levels deep the current menu item is from the top (top-level nav items are 1, their sub-items are 2, etc.)
* $navItem->subDepth : number of levels deep the current menu item is *compared to the next item in the list* (useful for determining how many <ul>'s to close in a nested list)
* $navItem->hasSubmenu : true/false -- if this item has one or more sub-items (sometimes useful for CSS styling)
* $navItem->isFirst : true/false -- if this is the first nav item *in its level* (for example, the first sub-item of a top-level item is TRUE)
* $navItem->isLast : true/false -- if this is the last nav item *in its level* (for example, the last sub-item of a top-level item is TRUE)
* $navItem->isCurrent : true/false -- if this nav item represents the page currently being viewed
* $navItem->inPath : true/false -- if this nav item represents a parent page of the page currently being viewed (also true for the page currently being viewed)
* $navItem->attrClass : Value of the 'nav_item_class' custom page attribute (if it exists and is set)
* $navItem->isHome : true/false -- if this nav item represents the home page
* $navItem->cID : collection id of the page this nav item represents
* $navItem->cObj : collection object of the page this nav item represents (use this if you need to access page properties and attributes that aren't already available in the $navItem object)
*/
/** For extra functionality, you can add the following page attributes to your site (via Dashboard > Pages & Themes > Attributes):
*
* 1) Handle: exclude_nav
* (This is the "Exclude From Nav" attribute that comes pre-installed with concrete5, so you do not need to add it yourself.)
* Functionality: If a page has this checked, it will not be included in the nav menu (and neither will its children / sub-pages).
*
* 2) Handle: exclude_subpages_from_nav
* Type: Checkbox
* Functionality: If a page has this checked, all of that pages children (sub-pages) will be excluded from the nav menu (but the page itself will be included).
*
* 3) Handle: replace_link_with_first_in_nav
* Type: Checkbox
* Functionality: If a page has this checked, clicking on it in the nav menu will go to its first child (sub-page) instead.
*
* 4) Handle: nav_item_class
* Type: Text
* Functionality: Whatever is entered into this textbox will be outputted as an additional CSS class for that page's nav item (NOTE: you must un-comment the "$ni->attrClass" code block in the CSS section below for this to work).
