[kepler-dev] FYI: Dataflow Exchange Language

[Edward A Lee]

FYI:  The lead on this, Shuvra S. Bhattacharyya, is a former
student of mine.  The SDF, PSDF and HDF implementations in Ptolemy II
are all totally aligned with this work... It's just a question of
syntax translation to get to and from MoML...
