Notes: Does not copy the indices, just keeps the pointer to the indices. The <A HREF="../IS/ISLocalToGlobalMappingDestroy.html#ISLocalToGlobalMappingDestroy">ISLocalToGlobalMappingDestroy</A>()
will free the space so it must be obtained with <A HREF="../Sys/PetscMalloc.html#PetscMalloc">PetscMalloc</A>() and it must not be freed elsewhere.
