- Mark those who are still not yet implemented:
- return an error
- have a grep-able string indicating that they are not yet
implemented
- ensure every function checks for init/finalize
- add more error checking to a bunch of functions
- unify the error checking -- it reflected about 3 different
[previous] error checking styles and MPI exception invocation styles
