-// NewInheritanceMatcher returns a matcher that matches based on the inheritance
-// chain.
-//
-// The matcher uses canonicalization and the parent relationship to find a
-// match. The resulting match will always be either Und or a language with the
-// same language and script as the requested language. It will not match
-// languages for which there is understood to be mutual or one-directional
-// intelligibility.
-//
-// A Match will indicate an Exact match if the language matches after
-// canonicalization and High if the matched tag is a parent.
