the intro page is loaded directly from the frameset
defined in index.html when the system is first entered.
But, reDisplay() gets called onLoad, so we dont want the
intro to get created twice. So if the form isnt defined, then the 
right frame has never been loaded, and is being loaded, so 
dont try to get it again.

But if the user causes the intro page to be redisplayed,
the intro page must be requested in the normal tocTab manner.
So the tocTab has a regular script calling entry for the intro page.
This is the script called. In those situations, the form is defined
so the intro is NOT being loaded already, so load it normally.

	added 6-20-2002 to stop server errors from requests
	that dont have the document fully loaded
	choice will get set either way. if the page isnt
	loaded, this returns and doesnt submit. 
	Then the body onLoad() event checks if choice
	is set. If so, immediately submit the form.

	6-26-2002
	the changed noted above caused the side effect that
	the browser back button had some odd effects.
	because choice is set when moving forward, when
	the user pressed back, the page with choice set would
	render in their browser, and CheckPrematureChoice()
	would notice choice is set, and submit the form.

	so, to alleviate this problem, i added the flag 
	premature_choice, which gets set when a premature 
	choice is made, as well as choice being set.
	then, CheckPremaureChoice() will check the flag
	before submitting. Any submission will cause 
	premature_choice to be unset. Then, when the user hits back
	premature_choice wont be set, and the form wont 
	automatically submit. I couldnt do this with choice,
	because choice needs to be set for the cgi handlers.
