Subject: Use headers instead of forward declarations.
X-Git-Tag: v8.5.0-rc1~1229^2~7
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=12964138f8471cd528d81a4266c35ea649c84360;p=dealii.git

Use headers instead of forward declarations.

We use typedefs inside of these classes so the header is necessary. The
header is currently included anyway through mapping_q1.h.
