/*
Prog Name: makeNav()
Purpose: Web Site Navigation

Instructions for use:

The function, makeNav(page, sec), accepts two parameters. The first, 'page', is the page name, sort of like a text ID that identifies the current page. It will highlight and gray out the current page's link. The second parameter, 'sec', is the section we are on (see below for a further explanation of what the sections are). This is a number between 0-8. This parameter takes precedence over the page variable which tells us what section we are in. If you want the page to
be highlighted, you must set 'sec' and give 'page' the text ID of the page within that section. If the text ID does not exist within that section, then the section will be opened without any pages highlighted (but the links will still be shown). If the section does not exist, all the sections will be collapsed and only the headers (section names) will be displayed.

Values for 'sec' parameter:
  0 = Collapse All
  1 = Melanoma Basics
  2 = What's My Risk?
  3 = Prevention
  4 = Early Detection
  5 = Making a Diagnosis
  6 = Staging Melanoma
  7 = Treatment
  8 = Life After Treatment
  9 = Utilities/Clinical Trials
