DirichletBC: Use specialization for Constraints instead of general case
34: auto columns = Constraints<Mat>::dirichletBC(matrix, dirichletNodes_);
There are specializations for this in the LinAlg implementations, yet only the generic implementation is included in the file.
This MR replaces the generic include
<amdis/linearalgebra/Constraints.hpp> with the specialization in
<amdis/linearalgebra/*/Constraints.hpp>. This is already done in
