Detailed Description

Helper class to automatically duplicate and free an MPI communicator.

This class duplicates the communicator given in the constructor using duplicate_communicator() and frees it automatically when this object gets destroyed by calling free_communicator(). You can access the wrapped communicator using operator*.

This class exists to easily allow duplicating communicators without having to worry when and how to free it after usage.
