		Full version, use it if you are pushing css to its functional limits, and/or are using 
		specialized javascript.
		
		Remember, always use method or object testing as your first choice, for example, if ( dom ) { statement; };
		
		This browser detection includes all possibilities I think for most browsers.
		Let me know if you find an error or a failure to properly detect, or if there
		is a relevant browser that has special needs for detection at our tech forum:
		http://techpatterns.com/forums/forum-11.html
		The main script is separated from the initial netscape 4 detection due to certain bugs in
		netscape 4 when it comes to unknown things like d.getElementById. The variable declarations
		of course are made first to make sure that all the variables are global through the page, 
		otherwise a javascript error will occur because you are trying to use an undeclared variable.
		
		We test for both browser type (ie, op, or moz/netscape > 6) and version number, then place 
		the version number into a variable which can be tested for < or > values, such as 
		if (moz && nu> 1.1){....statement....;}
		This seems quite reliable, especially for Opera and Mozilla, where there is no other
		easy way to get the actual version number.
		
		For more in depth discussion of css and browser issues go to:
		http://www.nic.fi/~tapio1/Teaching/DynamicMenusb.php#detections
