/*************************************************************
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:
