Package memcache provides functions to trace the bradfitz/gomemcache package (

    `WrapClient` will wrap a memcache `Client` and return a new struct with all the same methods, so should be seamless for existing applications. It also has an additional `WithContext` method which can be used to connect a span to an existing trace.
