[i know you think i didn't test it, but i did...that's confusing since now it
is erring for me, too]
How should this work, then?
My assumption is that the StringReplace actor should not fire/emit an output
token if it has no new token on the stringToEdit input port. This case happens
with the RExpression graphicsFileName actor is connected to the stringToEdit
port but graphics output is disabled (no file is passed to the stringToEdit
port).
Now the "Test" actor downstream from StringReplace isn't getting the token it
expects because there is no  token being sent.
