/*!
\brief Metafunction defining a type being either the specified tag, or one
    of the specified basetags if the type inherits from them.
\details Tags can inherit each other. A multi_point inherits, for example,
    both the multi_tag and the pointlike_tag. Often behaviour can be shared
    between different geometry types. A tag, found by the metafunction tag,
    can be casted to a more basic tag, and then dispatched by that tag.
\ingroup core
\tparam Tag The tag to be casted to one of the base tags
\tparam BaseTag First base tag
\tparam BaseTag2 Optional second base tag
\tparam BaseTag3 Optional third base tag
\tparam BaseTag4 Optional fourth base tag
\tparam BaseTag5 Optional fifth base tag
\tparam BaseTag6 Optional sixth base tag
\tparam BaseTag7 Optional seventh base tag
