Epetra_Comm Scan Sum function.
Take list of input values from all processors in the communicator, computes the scan sum and returns it to all processors such that processor i contains the sum of values from processor 0 up to and including processor i. Implemented in Epetra_MpiComm, and Epetra_SerialComm.
