TclStarIfc, which was originally written with the SDF domain in mind, works well for some types of DE stars. Specifically, any star with an input in the DE domain can use this class effectively. Consequently, a basic Tcl/Tk star,
TclScript, has been written for the DE domain.
TclScriptstar can have any number of input or output portholes. As of this writing, it will not work if it is instantiated with no inputs. The problem is that with no inputs, there will be no events to trigger a firing of the star. This will be corrected in the future.
