Subject: [PATCH] Use complete namespace for traits members (#330)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This prevents errors like this: error: ‘name’ is not a member of ‘pcl::detail::traits’; did you mean ‘pcl::traits::name’?
The error appears for newer PCL versions (everything after commit https://github.com/PointCloudLibrary/pcl/commit/d39d3d3300746b952997e5bd2742dac7482aa5ab), but this change should also be fully compatible with older PCL versions.
