12304	Incorrect documentation for boost::geometry::traits::ring_type	john.firebaugh@…	Barend Gehrels	"http://www.boost.org/doc/libs/1_61_0/libs/geometry/doc/html/geometry/reference/concepts/concept_polygon.html states:

> there must be a specialization of `traits::ring_type` defining the type of its exterior ring and interior rings as type

As far as I can tell, the specializations must actually be of `traits::ring_mutable_type` and `traits::ring_const_type`. There is no `traits::ring_type` template to specialize.

A similar issue exists with the documentation referring to `traits::interior_type` -- this should instead refer to `traits::interior_mutable_type` and `traits::interior_const_type`."	Bugs	new	To Be Determined	geometry	Boost 1.61.0	Problem			john.firebaugh@…
