Wiki text block rule for headings. For example:

{{{
	! Level one heading

	A paragraph in level 1.

	!! Level two heading

	A paragraph in level 2.
}}}

The bang `!` must be the first thing on the line. Any white space before the text of the heading is ignored.

A CSS can be applied to the heading as follows:

{{{
!{{myClass}} This heading will have the class `myClass`
}}}
