(Script under development - not yet functional)

What it does: 

When completed, this script will remove duplicate list items from section (e.g.: 
See also, holding bin, general concepts, list section, etc.). That is, it will 
remove from the current section all topics that exist anywhere else in the body 
of the page (not in templates).

This is useful for culling lists of links gathered to a holding area (in an outline)
awaiting placement into the outline. It can also help cleaning up the General concepts
sections, List sections, and See also sections of outlines.

Brief comments are provided within the source code below. For extensive explanatory 
notes on what the source code does and how it works, see the Script's workshop on 
the talk page. (Not ready yet.)

// ============== Set up ==============

// Start off with a bodyguard function to reserve the aliases mw and $
( function ( mw, $ ) {

    // we can now rely on mw and $ within the safety of our “bodyguard” function, to mean 
    // "mediawiki" and "jQuery", respectively

    // ============== ready() event listener/handler ==============
    // below is jQuery short-hand for $(document).ready(function() { ... });
    // it makes the rest of the script wait until the page's DOM is loaded and ready
    $(function() {
        
		// ============== activation filters ==============
        // Only activate on Vector skin
        if ( mw.config.get( 'skin' ) === 'vector' ) {

	        // Run this script only if "Outline " is in the page title
			if (document.title.indexOf("Outline ") != -1) {

				// End of set up
			
        	    // =================== Prep work =====================
				
				// Variable declarations, etc., go here

            	// ================= Core program ================= 

                $( function() {

					// BODY OF PROGRAM GOES HERE

				} );
