Subject: Add two brief class descriptions.
X-Git-Tag: v9.2.0-rc1~1458^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F8257%2Fhead;p=dealii.git

Add two brief class descriptions.

These are mentioned in other files and we need at least a stub here to
make the classes show up in doxygen.
