Memory leak in mpi_send (ouch) and mpi_group_incl
Multidimensional arrays were not working for mpi_send
Collectives were not working correctly for MPI-2 dynamicly created processes.
Version 1.12 added support for a number of additional routines and constants. The most significant additions are related to the support of dynamic MPI process creation. Version 1.13 adds even more support dynamic MPI process creation. These routines are available on systems that support MPI-2. The module can now return the MPI version number so the user can determine if the MPI-2 routines are supported.
Also, some additional MPI-1 routines were added in 1.12. These routines will be discussed first.
