/**
 * 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()}. For it to be fed to
 * {@code Class.getResource} instead, a leading slash would also have
 * to be prepended to the returned value.
 *
 * @param clazz the input class. A {@code null} value or the default
 *              (empty) package will result in an empty string ("") being returned.
 * @return a path which represents the package name
