In the current release, we added experimental support to compute intersections on \texttt{parallel::distributed::Triangulation} objects using \texttt{CGAL}~\cite{cgal-user-ref}. For this purpose we introduce a free function that computes intersections and relevant information for communication from \texttt{intersection\_requests}. \texttt{intersection\_requests} is a vector indicating entities of a given triangulation (in the form of \texttt{GridTools::Cache}) that intersections are computed upon. -Each entity (face or cell) is described by a vector of vertices.
