Hello,

I am getting close to wrapping up version 0.9 of the Dataflow library
(I think the 9 stands for how many times I've revamped the concepts
:-)).  The exciting new addition is that I have completed a simple GUI
dataflow editor!

I have never been more excited about making an app that doubles a number :-)

For this version, I want to iron things out a bit more (docs need a
ton of work) before I package it up (current code is available in the
sandbox and docs on website).  When the ironing is done I will request
review for the generic layer and Dataflow.Signals.  Dataflow.Blueprint
has a long way to go but I think it shows that the generic layer is
useful.  And the GUI shows that Dataflow.Blueprint is useful :-)

The GUI is built with FLTK (quick and easy), but I hope to switch it
to the new cppgui lib at some point.

Best regards,

Stjepan
