 ### Planned / TODO
 
-- Parallel random number engines (for use with `C++11` standard library distributions)
-- More parallel (standard) algorithms
-- Wrappers for non-blocking collectives
-- (maybe) serialization/de-serialization of non contiguous data types
-- macros for easy datatype creation and handling for custom/own structs and classes
-- Implementing and tuning different sorting algorithms
-- Communicator classes for different topologies
-- `mxx::env` similar to `boost::mpi::env` for wrapping `MPI_Init` and `MPI_Finalize`
-- Increase test coverage:
