[kepler-dev] Running workflows from command-line

Matt,

I suppose, conceptually it should still work as I could modify my own
individualistic and specific install and start scripts to install (a subset
of) Kepler/Core into a specific directory and run a workflow from command
line. 
That runs the ptolemy MomlSimpleApplication directly and does not use the
Run.java and loader of Kepler. Also it installs the jars from all modules'
lib/jar into one directory...

So I am a bit afraid of slowly becoming hopelessly outdated being stuck to
those scripts and face big problems in the future when I cannot hammer my
Kepler installation into a runnable shape anymore.

However, it runs my tiny test workflow (33ms) in 1.5. seconds including
loading Kepler. I like that.
