Applies maximum-principle-satisfying limiter to the solution. Using Zhang,Shu May 2010 Eq 3.8 and 3.9 we apply a limiter on the global solution

template<int dim, int nstate, typename real >

void PHiLiP::MaximumPrincipleLimiter< dim, nstate, real >::write_limited_solution	(	dealii::LinearAlgebra::distributed::Vector< double > &	solution,
