/**
 * Given an input class object, return a string which consists of the class's package name as a pathname, i.e., all dots ('.') are replaced by slashes ('/'). Neither a leading nor trailing slash is added. The result could be concatenated with a slash and the name of a resource, and fed directly to <code>ClassLoader.getResource()</code>. For it to be fed to <code>Class.getResource</code> instead, a leading slash would also have to be prepended to the returned value.

 *          the input class. A <code>null</code> value or the default (empty) package will result in an empty string ("") being returned.
