Molecules source code now available

Molecules source code now available
With the lifting of the Nondisclosure Agreement on the iPhone SDK, I'm pleased to finally make available the source code to Molecules. If you go to the main page for the application, you should now find a link to download the latest source tarball (for version 1.2) on the right-hand side. You can also download the source code here. I am working on migrating my personal Subversion setup so that you can check out the latest code and so that I can authorize contributors to commit fixes and additions.
