/*!
A submodule that defines a HTML class container `ClassData`, that a `DocTree` holds on to.
If a `class` reST directive is encountered, the classes specified by it
are stored in the `ClassData` container. If a reST text element *other* than `class`
is ran into, the classes stored in the container are given to the node corresponding
to thetext element.
