Wiki text block rule for assigning classes to paragraphs and other blocks. For example:

{{{
{{myClass{
This paragraph will have the CSS class `myClass`.

* The `<ul>` around this list will also have the class `myClass`
* List item 2

 }}}
}}}

Note that the opening and closing braces both must be immediately followed by a newline.
