<p>Gets the class name minus the package name from a {@code Class}.</p>

<p>Consider using the Java 5 API {@link Class#getSimpleName()} instead. 
The one known difference is that this code will return {@code "Map.Entry"} while 
the {@code java.lang.Class} variant will simply return {@code "Entry"}. </p>

@param cls  the class to get the short name for.
@return the class name without the package name or an empty string
