Foil 20 Modifications to mpiJava

From Object serialization for Marshalling Data in a Java Interface to MPI ACM Java Grande Meeting -- June 12-13 99. by Bryan Carpenter,Geoffrey C. Fox, Sung-Hoon Ko, Sang Lim
All mpiJava communications, including non-blocking modes and collective operations, now allow objects as base types.
Header + data decomposition complicates, eg, wait and test family.
Derived datatypes complicated.
Collective comms involve two phases if base type is OBJECT.
