| class | ParallelLibrary |
| the ParallelLibrary class has special access priveleges in order to streamline implementation | |
Container class for the data associated with a single level of communicator partitioning.
A list of these levels is contained in ParallelLibrary (ParallelLibrary::parallelLevels), which defines all of the parallelism levels across one or more multilevel parallelism configurations.

deallocate the communicators in this ParallelLevel
This appears to be more robust outside of the destructor due to interactions among managed deallocation and default deallocation (e.g., explicitly freeing a communicator and then default deallocating its handle).
