The RExpression actor is an actor designed to run an R script or function with inputs
and outputs determined by the ports created by the user. Port names will correspond to
R object names. The RExpression actor is modeled after the Ptolemy expression actor,
except that that instead of using a single mathematical expression in Ptolemy's
expression language, it uses a set of the more powerful, higher order expressions
available under R. Both input and output port will usually be added to the actor;
The names of these ports correspond to R variables used in the R script.
