- fixed visual editor sub app (barebones for now), so there is a visual view of things again (finally !)
* fixed various imports and structure of visual editor
* re-enabled the sub app in coffeescad.app
- started dissasembly / refact/ cleanup/conversion of CSG.js into more readable and modifiable code
 * converted the original javascript source to coffeescript through js2coffee & manually
 * refactored a lot of elements into slightly cleaned up classes
 * split the HUGE original codebase into a lot of smaller, maintainable and more readable modules
 * for now a lot of dependency issues between these modules need to be fixed
- continued cleanup work on CSG.coffee (port of csg.js)
 * removed require of csg.js as it was interfering with the new files
 * fixed a lot of import issues between the different new modules
 * overall cleanup of all the csg related files
