     * Reads a sequence of the following child nodes and attributes:
     *
     * Child Nodes:
     * - `add` - Adds a new style.
     *
     * Attributes:
     * - `as` - Name of the style.
     * - `extend` - Name of the style to inherit from.
     *
     * Each node contains another sequence of add and remove nodes with the following attributes:
     * - `as` - Name of the style (see properties of {@link CellStateStyle}).
     * - `value` - Value for the style.
     *
     * Instead of the value-attribute, one can put Javascript expressions into the node as follows if {@link allowEval} is `true`:
     * <add as="perimeter">Perimeter.RectanglePerimeter</add>
     *
     * A remove node will remove the entry with the name given in the as-attribute from the style.
     *
     * Example:
     *
     * ```javascript
     * <Stylesheet as="stylesheet">
     *   <add as="text">
     *     <add as="fontSize" value="12"/>
     *   </add>
     *   <add as="defaultVertex" extend="text">
     *     <add as="shape" value="rectangle"/>
     *   </add>
     * </Stylesheet>
     * ```
