- further experimentation with coffeescript ast manipulation
 * added coffeescript redux to experiment with direct ast generation from coffeescript

- updated main editor:
 * added a second code editor to track the generate code
 * updated bindings to match the update code-mirror element
 * more minor experimentation in tracking cursor position -> ast postion for coffeescript mode
- more experimentation with coffee-redux :
 * sadly not as practical as expected: no way to get sourcemaps outside node.js apparently
 * has a second transformation step csAST -> jsAST : not practical overall it would seem
- switching back to basic coffee-script for now
- migrated foo-editor out of index.html for cleanup
- started spliting ast manipulation & analysis code out into seperate js file
 * most of the ast related code is now in ast-manipulator.js
 * started cleaning up foo-editor accordingly
 * for now partially broken !
- added falafel to vendor scripts, for future use/experiments
