As I mentioned about a month ago, both JKstat and SolView were in line for some major refactoring.
I've done a bit of a spring clean on JKstat, so there's a new version - 0.25 - which has a lot of the cleanups and shuffling about that I had in mind. The class hierarchy has been restructured, code cleanup continues, and the more complex demos have been moved to SolView. The restructuring also allows the easy construction of a jar file containing just the API, so you don't need to drag in all the bloat associated with the browser, gui components, and demos.
The associated SolView release will follow shortly.
And thanks to Mike Duigou for a bunch of helpful fixes and suggestions!
