Memory leaks

[Jonas Lippuner]

There are some memory leaks in FleCSI. For example, running the simple 05-dense-data tutorial (with MPI backend) through valgrind yields

Can you do a --leak-check=full. AFIAK, many of these leaks actually came from MPI implementation itself.

@ollielo I think you're right. Looks like all the leaks are in MPI or another system library. I'm closing this issue.
