+Fixed: The function parallel::distributed::copy_triangulation() used to
+copy the reference to the attached SolutionTransfer instance, which resulted
+in calling the same SolutionTransfer instance multiple times if the 
+triangulation and the new triangulation are refined/coarsened independently.
+This has been fixed.
