/*************************************************************
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.
