please bring back the gui.name() feature

[GoogleCodeExporter]

What steps will reproduce the problem?
1. using gui.name() returns "is not a function"
2.
3.

What is the expected output? What do you see instead?

Apparently, an older version of dat.gui supported naming of the dat.gui, which 
is great when there are multiple dat'gui's in use.

This old documentation post explains that previous version:
https://lukeletters-datgui-alpha.googlecode.com/git-history/dbb4fa0ef0428380044e
825470e788dec1e37b86/index.html

In that version, using gui.name( 'text' ) would replace the "open controls" and 
"show controls" with the text supplied to the gui.name() function. 

What version of the product are you using? On what operating system?

"the latest available" version is being used, I got it today (6/4/2013) from 
http://dat-gui.googlecode.com/git/build/dat.gui.min.js

My serving operating system is Windows Server 2008 R3, running a 
apache/php/mysql/ja stack, and the runtime is a MacBookPro, OSX 10.7.5, Firefox 
21.0.

Please provide any additional information below.
