[xsl] all-XSLT implementation of Minesweeper

   I started this as a personal educational project to see how much of 
the data management and rules I could encode in XSLT.  The main page 
uses javascript to handle the mouse-events and to generate the random 
numbers.  Everything else is done in 3 different xslt files.  The first 
stylesheet takes a set of random numbers and a pair of min/max values 
and returns a list of elements representing a full grid. The next  style 
sheet transforms the list of nodes into grid of HTML buttons.  The third 
sheet returns the set of squares that are revealed when the user clicks 
on a square.   This is a recursive algorithm that looks for flags in 
squares bordering the square that was clicked.  That set is then sent to 
the same algorithm, and the template finds the flags bordering those 
squares, etc, until no more bordering flags are found. 

   I'll probably dress up the page a little this week with some 
explanatory text.

   I'd posted here a week or so ago regarding the speed difference 
between MS-IE and FireFox.  I posted a bug report to Mozilla about it 
which generated a lot of chatter among their developers regarding what 
performance improvements would be effective.

   I had a real problem with MS-IE in how it reacted to"deferred"  
<SCRIPT> blocks inside the xslt.  The problem seemed to do with when it 
chose to execute the script generated from the stylesheet. Firefox was 
much more predictable how it handled the <SCRIPT>. For the thing to work 
in IE,  I took all the script out of the stylesheet, which in this case 
seemed like the better approach anyway.
