[kepler-dev] Best practice for custom actor development

[Edward A. Lee]

I'm not sure how to set up the actor for use in Kepler,
but in Ptolemy, you don't need to recompile everything.
You can create a subclass of ptolemy.actor.TypedAtomicActor,
(to compile this, you need to specify to the compiler
to reference a Ptolemy jar file or classpath root).
Then when you start vergil (the UI), you can load this
actor as long as it is in the classpath... (you can specify
the classpath on the command line, if you want to put the
actor in some arbitrary place). To load it,
go to the Graph menu, and select Instantiate Entity.
Then just specify the full class name, relative to the
classpath.
