MPI Java wrapper design

The Java wrapper for MPI is designed according to the following criteria:

• The Java wrapper for MPI consists of a small set of classes with a lightweight functional interface to MPI. The classes are based upon the fundamental MPI object types (e.g. communicator, group, etc.).
• The Java wrapper language bindings provide a semantically correct interface to MPI.
• There is a one-to-one mapping between MPI functions and their Java wrapper bindings.
• To the greatest extent possible, the Java wrapper for MPI functions are methods functions of MPI classes.
