/*==============================================--=============================================NOTES
General Description
  Each page of this module consists of a 
  ..top logo
  ..next row is graphic and global navigation (pages available on all pages)
  ..next row is nav Path - ie a horizontal list of branches back to SSG home page
  ..body with specific content

Architecture
  top logo, global nav, and nav path are generated by javascript
  this allows top of page to be generated by single js file; allowing for global changes without 
    re-writing all pages
  this also means that debugging is more complex because html code is generated by javascript and 
    hence not displayed in view source
  information for generating nav path is carried from page to page in the window.name property
  ..going forward to link
  ....globalNavBranchHOME()                     //branch from home page to global page
  ....globalNavBranch()                         //branch from sub page to global page
  ....navToContentLink()
  ..click on top nav path(display of path back to main)
  ....navToNavPathLink()
  ......goes to page selected from link on nav path
  ......generates shorted nav path for revisited page being opened
  
  when page is loaded the name is parsed

Click on top global nav btn from any page
..calls globalNavBranchHOME() -or- globalNavBranch() the difference being the path to the target 
  page 
..passes the id for the button/link selected

..globalNavBranchHOME()/globalNavBranch()
....sets links page to selected page in global menu (in same window)
....specifically sets the window name

....as page loads,
......the JavaScript function 'genTopGlobalNav()' generates the top navigation section
........the parameter passed flags greyed out global link for the page currently shown
......the JavaScript function 'displNavPath()' 
........the code parses the window name to set up a 'nav path' which is the html code for links to
        the pages sequentially visisted starting with the main page (Student Survival Guide)
........there is a call to genPathLink()
..........this compares the name given to the link and assigns parameters for navToNavPathLink()
..........HERE ALL PAGES THAT LINK TO OTHER PAGES MUST BE LISTED

..Selecting link to page while in any page derived from main
....calls navToNavPathLink()
......sets url(which was passed as parameter) to next page
......appends name of next page (which was passed as parameter) to window.name 
......note that window.name is not a peristant property and must be set AFTER 
      window.location.href is set each time a new page is loaded
      
..Selecting link in the top nav path
....calls navToNavPathLink()
......goes to page selected from link on nav path (url filename is passes as parameter)
......generates shorted nav path for revisited page being opened (compares link name passed as 
      parameter to the current window name to create the shortened version for the page being 
      opened)
......
