/**  ---------------------------------------------
function:  	toggle  
purpose:  	Switch CSS class assignments for a collection of HTML elements between two CSS classes.
uses:		display / hide content, change styles, alter document format<b> 

properties: 
	trigger:	ID of the element which is the toggle switch. (click to change)
	tElement:	HTML tagname of the elements to be modified
	tClass:		a Class assigned to the elements to be modified 
				(use to uniquely identify the targets)
	tChoices:	two position array of the class names to be switched
				default: {'on', 'off'}
	tTriggerText: two position array of the text string to be swapped for the trigger link
				default: {'Turn Off', 'Turn On'}  
				These strings can contain HTML like an <img> tag
	name:		name of the toggle instance 
				-- change this parameter if you need more than one instance on a page

methods:
	flip:		changes all the HTML elements that match the tElement and tClass properties
				on the page from one tChoice class to the other.  Also swaps the tTriggerText
				
Sample Implementation:
trigger HTML Element:  
	<a id="displayChoice" href="#" class="poff" onclick="pLinks.flip(); return false;">Exclude SAS Press Titles</a>
invoking script:
    // initiaalize the toggle function
    var togc = ['pon', 'poff'];    // toggle off / on classes
    var togt = ['Exclude SAS Press Titles', 'Include SAS Press Titles'];  // toggle display text
    var pLinks = new toggle('displayChoice', 'TR', 'ponly', togc, togt);  // create toggle object
	// sample is from /documentation/cdl_main/92/docindex.html
	// supporting css styles for this sample are in misc.css
