Subject: Delete one unimplemented constructor.
X-Git-Tag: v9.0.0-rc1~1425^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F4605%2Fhead;p=dealii.git

Delete one unimplemented constructor.

While there, also let the compiler generate the default implementation
for copy constructors.
