/* test existance of a element in a form

if an element, i. e. a field, does not exist in a form, references that element
causes a run time error. (Note: undefined tests if an extant element has a
value, not whether or not it is declared.)

given a form object and a potential element name, this function determines if
the named element is in fact declared in the form.
returns true if the element exists, false otherwise

inputs: 
  theForm: an object. the form to investigate.
  theEle: a string. the element name to look for.
returns:
  true if the element exists on the form.
  false if not.

examples: 
    exist( document.gurn, "rcName" )
  determines if the element named rcName is an element of form gurn.
  
    function foz(){
      var formObj = document.gurn;
      with( formObj ){
        // references to known objects on the form
	if( exist( formObj, "rcName" ) ){
          // do things with rcName
	}
      }
    }

/* Menu system

Builds and handles menus. 
   The default menu color is blue. When the mouse is placed over the menu, the text
   turns red. 
   This is known to work in ns 3.5.3 and ie 6.0.2900.2180 running on  a pc with xp sp 2
   
   This system places constraints on the web site structure:
   1. Each page must be named <unique word>.shtml
   2. Each page must be in a subdirectory named <unique word>.
   
   For example, the calendar page is named
   calendar.shtml and lives in the subdirectory calendar.
   
   To add a new page, say gurn, with a corresponding menu:
   1. create the page named gurn.shtml
   2. create the subdirectory gurn. put gurn.shtml in this subdirectory 
   3. put the word "Gurn" in the menus array.
   4 the secon delement of the menus array is dependent on what you want to do: if clicking on the menu item is to open
   4a. the page gurn.shtml, put none in the second element.
   4b. a different page in the page set, put the lower case unique word of the page in
       the second element.
   4c. a completely different page, put the full url in the second element. it must have at least one /
