/**
* Sidebar Navigation Template Part
*
* Template part file that contains the sidebar navigation
* menu.
*
* By default, this sidebar navigation will output
* the descendant menu to the current top-level static
* Page, and will output up to three additional levels
* of Page hierarchy. The default menu is incredibly
* flexible and powerful, because it updates dynamically
* whenever the user changes Page hierarchy, by adding
* or removing Pages, or by changing the child-parent
* relationship for Pages.
*
* However, users can override this menu output by
* creating a custom navigation menu, and assigning it
* to the 'nav-sidebar' Theme location.
*
* This file is called by static Pages
*
