Initial Description





Get Function Name
============

This will only return (a string) if the object passed to getFunctionName is a function or an "object" function from IE.
The function does not rely on function.name if present as it can't always be trusted.

Examples:

    getFunctionName(function Foo(){}) == "Foo"
    getFunctionName(function(){}) == ""
