Improved, error-free and readable version of GreaseMonkey/TamperMonkey storage script "GM_SuperValue"

Same usage as GM_SuperValue original library (not git repository available for forking)

This library extends the Greasemonkey GM_setValue and GM_getValue functions to handle any javascript variable type.

Add it to your GM script with:

// @require http://userscripts.org/scripts/source/107941.user.js

Usage:

GM_SuperValue.set(varName, varValue);  
var x = GM_SuperValue.get(varName, defaultValue);  

Test mode:

GM_SuperValue.runTestCases  (bUseConsole);

Here is the original script page for reference.
