[Data-modeling] Processes

[Iain Sproat]

Jeff - thanks again for the advice.  I've made a "Process state" type with
properties "input into" and "output of".
Michael - Ordering: I thought about this but decided against it as processes
can have cyclic loops, and loops within loops - the Nitrogen
cycle<http://process.freebase.com/view/en/nitrogen_cycle>is a very
good example of this.
