Subject: Remove HyperShellBoundary from step-32.
X-Git-Tag: v9.0.0-rc1~142^2~4
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1422509534d6f6b83336e4a3043b2531d855cb4a;p=dealii.git

Remove HyperShellBoundary from step-32.

As of ff7cc4c8075 this functionality is also in Manifold, so we do not
need to use a Boundary object here.
