Just FYI, I just merged the window declaration feature into the master branch. I will write a proper blog post later about the feature itself, but be aware that it has a side-effect of breaking the current serialization of any kbase/ksession that uses sliding windows until we re-implement the serialization framework in a couple weeks.

   Serialization of kbases/ksessions that don't use sliding windows should not be affected.
