This avoids also multiple testing using same input data.

Move the code for creating parallel MeshComponentMap
to its own method.

Adding a single space in incorrectly broken lines.

The fmt library happily accepts std::string without
any conversions.

Mostly in the file headers.

find *Lib -type f | xargs sed -i 'N;s%^\s\+\*\n\(\s\+\*/\)%\1%'

Fixes multiple copyright messages in the doxygen docu.

ag '\\file' -L --ignore=ThirdParty *Lib |xargs  sed -i 's/\(.*\)\\copyright/\1\\file\n\1\\copyright/'

If the boundary mesh is larger then the definition region
of the bulk component, then a nop is returned.
This usually indicates wrong geometry or something horrible.

Clang format run on near-the-header lines.

Happy New Year

This has some follow-up changes.

Don't repeat typename in emplace_back.
