Includes all MPI functions supported by Open MPI, including MPI-3 functions (as of about 2 weeks ago). Many changes compared to the prior generation of Java bindings; not much is left from the prior generation, actually. The changes include (but are not limited to): * Add support for more than just a subset of MPI-1 functions * Use typical Java case for symbol names * Support Java Direct buffers (giving darn-near "native C" performance) * Support "type struct" better than the prior generation * Make more of an effort for the Java bindings to be a thin layer over the back-end C bindings * ...and more A proper README with more information about what is supported, how to use these bindings, etc. will be committed shortly. This commit was SVN r29263.
