Destroy a MapReduce object

MapReduce::~MapReduce() 

This destroys a previously created MapReduce object, freeing all the memory it allocated internally to store keys and values.

If you created the MapReduce object in this manner:

MapReduce *mr = new MapReduce(MPI_COMM_WORLD); 

then you should destroy it with

delete mr 

If you created the MapReduce object in this manner:

MapReduce mr(MPI_COMM_WORLD); 

then it will be destroyed automatically when the "mr" variable goes out of scope.
