+ * Generates an array of CSS classes that can be applied in a theme.

+ * The CSS classes can be applied to the body tag of the page and used to
+ * perform mutations through CSS instead of purely code. This should be called
+ * from the theme and the classes should be placed on the body tag. This can be
+ * done inside phptemplate_body_class(). The classes can be turned into a
+ * string with the following sniplet.
+ * <code>
+ *   implode(' ', $classes);
+ * </code>
+ *
+ * @return array List of CSS classes representing the current mutation state.
+ *   The classes follow the format: "multivariate-[GROUP]-[STATE]".

+ *       'multivaraite-0-2',
+ *       'multivaraite-1-1',
+ *     );
