		You can have this script, use it to your hearts content and you can delete all the comments
		from this paragraph and below - just make sure you leave the credit in for the first three guys
		since they did the really hard work and I just stuck it together.


		the sorttable function as well as make pretty and rank functions are basically untouched except
		for an improvement to the sorttable function which allows for greater accuracy in the search
		as it looks at each cell in order from left to right in a row instead of just a secondary cell
		for ordering matches in the cell to be sorted.  I did add a couple of extra parameters to the sorttable
		function that let you set some things into motion optionally.


		Basically Mike Halls sorttable works pretty well, however, it had two shortcomings:
		1. the first time I tried to sort a column it was kind of slow and unresponsive - i think because
		of the makepretty call.
		2. you had to insert javascript code into each column of every table you wanted sortable - and I prefer a more
		unobtrusive DHTML (an idea i first learned about at http://youngpup.net/Mastah.aspx?year=2001&filename=labels)
		experience personally.

		so what goes on here?

		1. sorttables_init finds all the tables with the class of sortable and a unique ID (important to have both!)
			a. takes the first row of each of the sortable tables on the page and turns it into a header row.
			b. in the header row each cell that is of class sortColumn is then fixed with an onclick event that calls the ts_resortTable script
			c. then calls the makepretty function to add "zebra-stripes" to the table and passes in an invalid column id so no column is noted
				as sorted by default.
		2. ts_resortTable figures out what column was clicked on by looking at the DOM with a starting point at the link that was clicked
		3. ts_resortTable then calls the sortTable script which actually does all the sorting
		4. when sortTable is complete it calls makepretty again to fix up the zebra-stripes and voila, you have a nicely ordered, pretty table
		5. whats more, your page has ZERO javascript on it.  just nice structurally sound markup! pretty cool eh?


		some caveats:
		this stuff expects good valid html. what does this mean?
			A. your table needs an id value - and that id really needs to be unique.
			B. your table needs to be structurally sound 
			c. if you want makepretty to work you need some classes defined:
				alternateRow
				sortedColumn
			d. remember to give your table the class name sortable and each column you want sortable the classname sortColumn
