Allowing not only a zero value to be applied to the inactive
nodes but also heterogeneous, time-dependent values.

Adding a single space in incorrectly broken lines.

Either time interval is given w/o line segment, which is
unused for whole material ids blocks deactivation *or*
a curve and line segment must be given.

Creating the curve for time interval s.t. the whole material ids group
is deactivated, as it was for the time interval case.

Code simplification and one less dereferencing at run time.

The name reflects the special nature of the nodes,
namely that these are nodes not touching the active
elements.

Reducing scope, using algorithms.

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

Either by renaming or removing the variable or adding
an extra scope to the top variable.

CPPCheck warning type: shadowVar.

due to its std::unique_ptr type instance.
